FIELD

The present disclosure relates generally to computer user interfaces,and more specifically to techniques for interacting with userinterfaces.

BACKGROUND

Reduced-size electronic devices (e.g., devices that are smaller thantypical cellular phones such as smart watches) that are configured to beworn by a user can allow a user to view and respond to various types ofalerts, such as text messages, emails, voicemails, and calendar alerts.User interfaces that enable a reduced-size electronic device to beefficiently used for viewing and responding to alerts are desirable.

BRIEF SUMMARY

Some techniques for interacting with electronic devices, however, aregenerally cumbersome and inefficient. For example, some existingtechniques use a complex and time-consuming user interface, which caninclude multiple button presses or finger touches. In the case ofdevices worn on a user's arm (e.g., a smart watch) operation of thedevice via a touchscreen interface effectively requires the use of bothof the users hands, restricting their use for other purposes. Moreover,existing techniques require more time than necessary, wasting user timeand device energy. This latter consideration is particularly importantin battery-operated devices.

Accordingly, the present techniques provide electronic devices withfaster, more efficient methods and interfaces for interacting with thedevices without touching display screens or other physical inputmechanisms. Such methods and interfaces optionally complement or replaceother methods for interacting with the devices. Such methods andinterfaces reduce the cognitive burden on a user and produce a moreefficient human-machine interface. For battery-operated computingdevices, such methods and interfaces conserve power and increase thetime between battery charges.

Although the following description uses terms “first,” “second,” etc. todescribe various elements, these elements should not be limited by theterms. These terms are only used to distinguish one element fromanother. For example, a first touch could be termed a second touch, and,similarly, a second touch could be termed a first touch, withoutdeparting from the scope of the various described embodiments. The firsttouch and the second touch are both touches, but they are not the sametouch.

The terminology used in the description of the various describedembodiments herein is for the purpose of describing particularembodiments only and is not intended to be limiting. As used in thedescription of the various described embodiments and the appendedclaims, the singular forms “a,” “an,” and “the” are intended to includethe plural forms as well, unless the context clearly indicatesotherwise. It will also be understood that the term “and/or” as usedherein refers to and encompasses any and all possible combinations ofone or more of the associated listed items. It will be furtherunderstood that the terms “includes,” “including,” “comprises,” and/or“comprising,” when used in this specification, specify the presence ofstated features, integers, steps, operations, elements, and/orcomponents, but do not preclude the presence or addition of one or moreother features, integers, steps, operations, elements, components,and/or groups thereof.

The term “if” is, optionally, construed to mean “when” or “upon” or “inresponse to determining” or “in response to detecting,” depending on thecontext. Similarly, the phrase “if it is determined” or “if [a statedcondition or event] is detected” is, optionally, construed to mean “upondetermining” or “in response to determining” or “upon detecting [thestated condition or event]” or “in response to detecting [the statedcondition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, andassociated processes for using such devices are described. In someembodiments, the device is a portable communications device, such as amobile telephone, that also contains other functions, such as PDA and/ormusic player functions. Exemplary embodiments of portable multifunctiondevices include, without limitation, the iPhone®, iPod Touch®, and iPad®devices from Apple Inc. of Cupertino, Calif. Other portable electronicdevices, such as laptops or tablet computers with touch-sensitivesurfaces (e.g., touch screen displays and/or touchpads), are,optionally, used. It should also be understood that, in someembodiments, the device is not a portable communications device, but isa desktop computer with a touch-sensitive surface (e.g., a touch screendisplay and/or a touchpad).

In the discussion that follows, an electronic device that includes adisplay and a touch-sensitive surface is described. It should beunderstood, however, that the electronic device optionally includes oneor more other physical user-interface devices, such as a physicalkeyboard, a mouse, and/or a joystick.

The device typically supports a variety of applications, such as one ormore of the following: a drawing application, a presentationapplication, a word processing application, a website creationapplication, a disk authoring application, a spreadsheet application, agaming application, a telephone application, a video conferencingapplication, an e-mail application, an instant messaging application, aworkout support application, a photo management application, a digitalcamera application, a digital video camera application, a web browsingapplication, a digital music player application, and/or a digital videoplayer application.

The various applications that are executed on the device optionally useat least one common physical user-interface device, such as thetouch-sensitive surface. One or more functions of the touch-sensitivesurface as well as corresponding information displayed on the deviceare, optionally, adjusted and/or varied from one application to the nextand/or within a respective application. In this way, a common physicalarchitecture (such as the touch-sensitive surface) of the deviceoptionally supports the variety of applications with user interfacesthat are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices withtouch-sensitive displays. FIG. 1A is a block diagram illustratingportable multifunction device 100 with touch-sensitive display system112 in accordance with some embodiments. Touch-sensitive display 112 issometimes called a “touch screen” for convenience and is sometimes knownas or called a “touch-sensitive display system.” Device 100 includesmemory 102 (which optionally includes one or more computer-readablestorage mediums), memory controller 122, one or more processing units(CPUs) 120, peripherals interface 118, RF circuitry 108, audio circuitry110, speaker 111, microphone 113, input/output (I/O) subsystem 106,other input control devices 116, and external port 124. Device 100optionally includes one or more optical sensors 164. Device 100optionally includes one or more contact intensity sensors 165 fordetecting intensity of contacts on device 100 (e.g., a touch-sensitivesurface such as touch-sensitive display system 112 of device 100).Device 100 optionally includes one or more tactile output generators 167for generating tactile outputs on device 100 (e.g., generating tactileoutputs on a touch-sensitive surface such as touch-sensitive displaysystem 112 of device 100 or touchpad 355 of device 300). Thesecomponents optionally communicate over one or more communication busesor signal lines 103.

As used in the specification and claims, the term “intensity” of acontact on a touch-sensitive surface refers to the force or pressure(force per unit area) of a contact (e.g., a finger contact) on thetouch-sensitive surface, or to a substitute (proxy) for the force orpressure of a contact on the touch-sensitive surface. The intensity of acontact has a range of values that includes at least four distinctvalues and more typically includes hundreds of distinct values (e.g., atleast 256). Intensity of a contact is, optionally, determined (ormeasured) using various approaches and various sensors or combinationsof sensors. For example, one or more force sensors underneath oradjacent to the touch-sensitive surface are, optionally, used to measureforce at various points on the touch-sensitive surface. In someimplementations, force measurements from multiple force sensors arecombined (e.g., a weighted average) to determine an estimated force of acontact. Similarly, a pressure-sensitive tip of a stylus is, optionally,used to determine a pressure of the stylus on the touch-sensitivesurface. Alternatively, the size of the contact area detected on thetouch-sensitive surface and/or changes thereto, the capacitance of thetouch-sensitive surface proximate to the contact and/or changes thereto,and/or the resistance of the touch-sensitive surface proximate to thecontact and/or changes thereto are, optionally, used as a substitute forthe force or pressure of the contact on the touch-sensitive surface. Insome implementations, the substitute measurements for contact force orpressure are used directly to determine whether an intensity thresholdhas been exceeded (e.g., the intensity threshold is described in unitscorresponding to the substitute measurements). In some implementations,the substitute measurements for contact force or pressure are convertedto an estimated force or pressure, and the estimated force or pressureis used to determine whether an intensity threshold has been exceeded(e.g., the intensity threshold is a pressure threshold measured in unitsof pressure). Using the intensity of a contact as an attribute of a userinput allows for user access to additional device functionality that mayotherwise not be accessible by the user on a reduced-size device withlimited real estate for displaying affordances (e.g., on atouch-sensitive display) and/or receiving user input (e.g., via atouch-sensitive display, a touch-sensitive surface, or aphysical/mechanical control such as a knob or a button).

As used in the specification and claims, the term “tactile output”refers to physical displacement of a device relative to a previousposition of the device, physical displacement of a component (e.g., atouch-sensitive surface) of a device relative to another component(e.g., housing) of the device, or displacement of the component relativeto a center of mass of the device that will be detected by a user withthe user's sense of touch. For example, in situations where the deviceor the component of the device is in contact with a surface of a userthat is sensitive to touch (e.g., a finger, palm, or other part of auser's hand), the tactile output generated by the physical displacementwill be interpreted by the user as a tactile sensation corresponding toa perceived change in physical characteristics of the device or thecomponent of the device. For example, movement of a touch-sensitivesurface (e.g., a touch-sensitive display or trackpad) is, optionally,interpreted by the user as a “down click” or “up click” of a physicalactuator button. In some cases, a user will feel a tactile sensationsuch as an “down click” or “up click” even when there is no movement ofa physical actuator button associated with the touch-sensitive surfacethat is physically pressed (e.g., displaced) by the user's movements. Asanother example, movement of the touch-sensitive surface is, optionally,interpreted or sensed by the user as “roughness” of the touch-sensitivesurface, even when there is no change in smoothness of thetouch-sensitive surface. While such interpretations of touch by a userwill be subject to the individualized sensory perceptions of the user,there are many sensory perceptions of touch that are common to a largemajority of users. Thus, when a tactile output is described ascorresponding to a particular sensory perception of a user (e.g., an “upclick,” a “down click,” “roughness”), unless otherwise stated, thegenerated tactile output corresponds to physical displacement of thedevice or a component thereof that will generate the described sensoryperception for a typical (or average) user.

In some embodiments, some or all ofthe visual output optionally corresponds to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor, or set ofsensors that accepts input from the user based on haptic and/or tactilecontact. Touch screen 112 and display controller 156 (along with anyassociated modules and/or sets of instructions in memory 102) detectcontact (and any movement or breaking of the contact) on touch screen112 and convert the detected contact into interaction withuser-interface objects (e.g., one or more soft keys, icons, web pages,or images) that are displayed on touch screen 112. In an exemplaryembodiment, a point of contact between touch screen 112 and the usercorresponds to a finger of the user.

Touch screen 112 optionally uses LCD (liquid crystal display)technology, LPD (light emitting polymer display) technology, or LED(light emitting diode) technology, although other display technologiesare used in other embodiments. Touch screen 112 and display controller156 optionally detect contact and any movement or breaking thereof usingany of a plurality of touch sensing technologies now known or laterdeveloped, including but not limited to capacitive, resistive, infrared,and surface acoustic wave technologies, as well as other proximitysensor arrays or other elements for determining one or more points ofcontact with touch screen 112.

No. 6,323,846 (Westerman et al.), U.S. Pat.No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932(Westerman), and/or U.S. Patent Publication 2002/0015024A1, each ofwhich is hereby incorporated by reference in its entirety. However,touch screen 112 displays visual output from device 100, whereastouch-sensitive touchpads do not provide visual output.

A touch-sensitive display in some embodiments of touch screen 112 isdescribed in the following applications: (1) U.S. patent applicationSer. No. 11/381,313, “Multipoint Touch Surface Controller,” filed May 2,2006; (2) U.S. patent application Ser. No. 10/840,862, “MultipointTouchscreen,” filed May 6, 2004; (3) U.S. patent application Ser.

The user optionally makes contact with touchscreen 112 using any suitable object or appendage, such as a stylus, afinger, and so forth. In some embodiments, the user interface isdesigned to work primarily with finger-based contacts and gestures,which can be less precise than stylus-based input due to the larger areaof contact of a finger on the touch screen. In some embodiments, thedevice translates the rough finger-based input into a precisepointer/cursor position or command for performing the actions desired bythe user.

In some embodiments, at least one tactile outputgenerator is collocated with, or proximate to, a touch-sensitive surface(e.g., touch-sensitive display system 112) and, optionally, generates atactile output by moving the touch-sensitive surface vertically (e.g.,in/out of a surface of device 100) or laterally (e.g., back and forth inthe same plane as a surface of device 100). In some embodiments, atleast one tactile output generator sensor is located on the back ofdevice 100, opposite touch screen display 112, which is located on thefront of device 100.

Contact/motion module 130 optionally detects contact with touch screen112 (in conjunction with display controller 156) and othertouch-sensitive devices (e.g., a touchpad or physical click wheel).Contact/motion module 130 includes various software components forperforming various operations related to detection of contact, such asdetermining if contact has occurred (e.g., detecting a finger-downevent), determining an intensity of the contact (e.g., the force orpressure of the contact or a substitute for the force or pressure of thecontact), determining if there is movement of the contact and trackingthe movement across the touch-sensitive surface (e.g., detecting one ormore finger-dragging events), and determining if the contact has ceased(e.g., detecting a finger-up event or a break in contact).Contact/motion module 130 receives contact data from the touch-sensitivesurface. Determining movement of the point of contact, which isrepresented by a series of contact data, optionally includes determiningspeed (magnitude), velocity (magnitude and direction), and/or anacceleration (a change in magnitude and/or direction) of the point ofcontact. These operations are, optionally, applied to single contacts(e.g., one finger contacts) or to multiple simultaneous contacts (e.g.,“multitouch”/multiple finger contacts). In some embodiments,contact/motion module 130 and display controller 156 detect contact on atouchpad.

In some embodiments, contact/motion module 130 uses a set of one or moreintensity thresholds to determine whether an operation has beenperformed by a user (e.g., to determine whether a user has “clicked” onan icon). In some embodiments, at least a subset of the intensitythresholds are determined in accordance with software parameters (e.g.,the intensity thresholds are not determined by the activation thresholdsof particular physical actuators and can be adjusted without changingthe physical hardware of device 100). For example, a mouse “click”threshold of a trackpad or touch screen display can be set to any of alarge range of predefined threshold values without changing the trackpador touch screen display hardware. Additionally, in some implementations,a user of the device is provided with software settings for adjustingone or more of the set of intensity thresholds (e.g., by adjustingindividual intensity thresholds and/or by adjusting a plurality ofintensity thresholds at once with a system-level click “intensity”parameter).

Contact/motion module 130 optionally detects a gesture input by a user.Different gestures on the touch-sensitive surface have different contactpatterns (e.g., different motions, timings, and/or intensities ofdetected contacts). Thus, a gesture is, optionally, detected bydetecting a particular contact pattern. For example, detecting a fingertap gesture includes detecting a finger-down event followed by detectinga finger-up (liftoff) event at the same position (or substantially thesame position) as the finger-down event (e.g., at the position of anicon). As another example, detecting a finger swipe gesture on thetouch-sensitive surface includes detecting a finger-down event followedby detecting one or more finger-dragging events, and subsequentlyfollowed by detecting a finger-up (liftoff) event.

No. 11/968,067, “PortableMultifunction Device, Method, and Graphical User Interface for PlayingOnline Videos,” filed Dec. 31, 2007, the contents of which are herebyincorporated by reference in their entirety.

Each of the above-identified modules and applications corresponds to aset of executable instructions for performing one or more functionsdescribed above and the methods described in this application (e.g., thecomputer-implemented methods and other information processing methodsdescribed herein). These modules (e.g., sets of instructions) need notbe implemented as separate software programs, procedures, or modules,and thus various subsets of these modules are, optionally, combined orotherwise rearranged in various embodiments. For example, video playermodule is, optionally, combined with music player module into a singlemodule (e.g., video and music player module 152, FIG. 1A). In someembodiments, memory 102 optionally stores a subset of the modules anddata structures identified above. Furthermore, memory 102 optionallystores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of apredefined set of functions on the device is performed exclusivelythrough a touch screen and/or a touchpad. By using a touch screen and/ora touchpad as the primary input control device for operation of device100, the number of physical input control devices (such as push buttons,dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through atouch screen and/or a touchpad optionally include navigation betweenuser interfaces. In some embodiments, the touchpad, when touched by theuser, navigates device 100 to a main, home, or root menu from any userinterface that is displayed on device 100. In such embodiments, a “menubutton” is implemented using a touchpad. In some other embodiments, themenu button is a physical push button or other physical input controldevice instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for eventhandling in accordance with some embodiments. In some embodiments,memory 102 (FIG. 1A) or 370 (FIG. 3 ) includes event sorter 170 (e.g.,in operating system 126) and a respective application 136-1 (e.g., anyof the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines theapplication 136-1 and application view 191 of application 136-1 to whichto deliver the event information. Event sorter 170 includes eventmonitor 171 and event dispatcher module 174. In some embodiments,application 136-1 includes application internal state 192, whichindicates the current application view(s) displayed on touch-sensitivedisplay 112 when the application is active or executing. In someembodiments, device/global internal state 157 is used by event sorter170 to determine which application(s) is (are) currently active, andapplication internal state 192 is used by event sorter 170 to determineapplication views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additionalinformation, such as one or more of: resume information to be used whenapplication 136-1 resumes execution, user interface state informationthat indicates information being displayed or that is ready for displayby application 136-1, a state queue for enabling the user to go back toa prior state or view of application 136-1, and a redo/undo queue ofprevious actions taken by the user.

Event monitor 171 receives event information from peripherals interface118. Event information includes information about a sub-event (e.g., auser touch on touch-sensitive display 112, as part of a multi-touchgesture). Peripherals interface 118 transmits information it receivesfrom I/O subsystem 106 or a sensor, such as proximity sensor 166,accelerometer(s) 168, and/or microphone 113 (through audio circuitry110). Information that peripherals interface 118 receives from I/Osubsystem 106 includes information from touch-sensitive display 112 or atouch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripheralsinterface 118 at predetermined intervals. In response, peripheralsinterface 118 transmits event information. In other embodiments,peripherals interface 118 transmits event information only when there isa significant event (e.g., receiving an input above a predeterminednoise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit viewdetermination module 172 and/or an active event recognizer determinationmodule 173.

Hit view determination module 172 provides software procedures fordetermining where a sub-event has taken place within one or more viewswhen touch-sensitive display 112 displays more than one view. Views aremade up of controls and other elements that a user can see on thedisplay.

Another aspect of the user interface associated with an application is aset of views, sometimes herein called application views or userinterface windows, in which information is displayed and touch-basedgestures occur. The application views (of a respective application) inwhich a touch is detected optionally correspond to programmatic levelswithin a programmatic or view hierarchy of the application. For example,the lowest level view in which a touch is detected is, optionally,called the hit view, and the set of events that are recognized as properinputs are, optionally, determined based, at least in part, on the hitview of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related tosub-events of a touch-based gesture. When an application has multipleviews organized in a hierarchy, hit view determination module 172identifies a hit view as the lowest view in the hierarchy which shouldhandle the sub-event. In most circumstances, the hit view is the lowestlevel view in which an initiating sub-event occurs (e.g., the firstsub-event in the sequence of sub-events that form an event or potentialevent). Once the hit view is identified by the hit view determinationmodule 172, the hit view typically receives all sub-events related tothe same touch or input source for which it was identified as the hitview.

Active event recognizer determination module 173 determines which viewor views within a view hierarchy should receive a particular sequence ofsub-events. In some embodiments, active event recognizer determinationmodule 173 determines that only the hit view should receive a particularsequence of sub-events. In other embodiments, active event recognizerdetermination module 173 determines that all views that include thephysical location of a sub-event are actively involved views, andtherefore determines that all actively involved views should receive aparticular sequence of sub-events. In other embodiments, even if touchsub-events were entirely confined to the area associated with oneparticular view, views higher in the hierarchy would still remain asactively involved views.

Event dispatcher module 174 dispatches the event information to an eventrecognizer (e.g., event recognizer 180). In embodiments including activeevent recognizer determination module 173, event dispatcher module 174delivers the event information to an event recognizer determined byactive event recognizer determination module 173. In some embodiments,event dispatcher module 174 stores in an event queue the eventinformation, which is retrieved by a respective event receiver 182.

In some embodiments, operating system 126 includes event sorter 170.Alternatively, application 136-1 includes event sorter 170. In yet otherembodiments, event sorter 170 is a stand-alone module, or a part ofanother module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of eventhandlers 190 and one or more application views 191, each of whichincludes instructions for handling touch events that occur within arespective view of the application's user interface. Each applicationview 191 of the application 136-1 includes one or more event recognizers180. Typically, a respective application view 191 includes a pluralityof event recognizers 180. In other embodiments, one or more of eventrecognizers 180 are part of a separate module, such as a user interfacekit (not shown) or a higher level object from which application 136-1inherits methods and other properties. In some embodiments, a respectiveevent handler 190 includes one or more of: data updater 176, objectupdater 177, GUI updater 178, and/or event data 179 received from eventsorter 170. Event handler 190 optionally utilizes or calls data updater176, object updater 177, or GUI updater 178 to update the applicationinternal state 192. Alternatively, one or more of the application views191 include one or more respective event handlers 190. Also, in someembodiments, one or more of data updater 176, object updater 177, andGUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g.,event data 179) from event sorter 170 and identifies an event from theevent information. Event recognizer 180 includes event receiver 182 andevent comparator 184. In some embodiments, event recognizer 180 alsoincludes at least a subset of: metadata 183, and event deliveryinstructions 188 (which optionally include sub-event deliveryinstructions).

Event receiver 182 receives event information from event sorter 170. Theevent information includes information about a sub-event, for example, atouch or a touch movement. Depending on the sub-event, the eventinformation also includes additional information, such as location ofthe sub-event. When the sub-event concerns motion of a touch, the eventinformation optionally also includes speed and direction of thesub-event. In some embodiments, events include rotation of the devicefrom one orientation to another (e.g., from a portrait orientation to alandscape orientation, or vice versa), and the event informationincludes corresponding information about the current orientation (alsocalled device attitude) of the device.

Event comparator 184 compares the event information to predefined eventor sub-event definitions and, based on the comparison, determines anevent or sub-event, or determines or updates the state of an event orsub-event. In some embodiments, event comparator 184 includes eventdefinitions 186. Event definitions 186 contain definitions of events(e.g., predefined sequences of sub-events), for example, event 1(187-1), event 2 (187-2), and others. In some embodiments, sub-events inan event (187) include, for example, touch begin, touch end, touchmovement, touch cancellation, and multiple touching. In one example, thedefinition for event 1 (187-1) is a double tap on a displayed object.The double tap, for example, comprises a first touch (touch begin) onthe displayed object for a predetermined phase, a first liftoff (touchend) for a predetermined phase, a second touch (touch begin) on thedisplayed object for a predetermined phase, and a second liftoff (touchend) for a predetermined phase. In another example, the definition forevent 2 (187-2) is a dragging on a displayed object. The dragging, forexample, comprises a touch (or contact) on the displayed object for apredetermined phase, a movement of the touch across touch-sensitivedisplay 112, and liftoff of the touch (touch end). In some embodiments,the event also includes information for one or more associated eventhandlers 190.

In some embodiments, event definition 187 includes a definition of anevent for a respective user-interface object. In some embodiments, eventcomparator 184 performs a hit test to determine which user-interfaceobject is associated with a sub-event. For example, in an applicationview in which three user-interface objects are displayed ontouch-sensitive display 112, when a touch is detected on touch-sensitivedisplay 112, event comparator 184 performs a hit test to determine whichof the three user-interface objects is associated with the touch(sub-event). If each displayed object is associated with a respectiveevent handler 190, the event comparator uses the result of the hit testto determine which event handler 190 should be activated. For example,event comparator 184 selects an event handler associated with thesub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event (187) alsoincludes delayed actions that delay delivery of the event informationuntil after it has been determined whether the sequence of sub-eventsdoes or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series ofsub-events do not match any of the events in event definitions 186, therespective event recognizer 180 enters an event impossible, eventfailed, or event ended state, after which it disregards subsequentsub-events of the touch-based gesture. In this situation, other eventrecognizers, if any, that remain active for the hit view continue totrack and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata183 with configurable properties, flags, and/or lists that indicate howthe event delivery system should perform sub-event delivery to activelyinvolved event recognizers. In some embodiments, metadata 183 includesconfigurable properties, flags, and/or lists that indicate how eventrecognizers interact, or are enabled to interact, with one another. Insome embodiments, metadata 183 includes configurable properties, flags,and/or lists that indicate whether sub-events are delivered to varyinglevels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates eventhandler 190 associated with an event when one or more particularsub-events of an event are recognized. In some embodiments, a respectiveevent recognizer 180 delivers event information associated with theevent to event handler 190. Activating an event handler 190 is distinctfrom sending (and deferred sending) sub-events to a respective hit view.In some embodiments, event recognizer 180 throws a flag associated withthe recognized event, and event handler 190 associated with the flagcatches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-eventdelivery instructions that deliver event information about a sub-eventwithout activating an event handler. Instead, the sub-event deliveryinstructions deliver event information to event handlers associated withthe series of sub-events or to actively involved views. Event handlersassociated with the series of sub-events or with actively involved viewsreceive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used inapplication 136-1. For example, data updater 176 updates the telephonenumber used in contacts module 137, or stores a video file used in videoplayer module. In some embodiments, object updater 177 creates andupdates objects used in application 136-1. For example, object updater177 creates a new user-interface object or updates the position of auser-interface object. GUI updater 178 updates the GUI. For example, GUIupdater 178 prepares display information and sends it to graphics module132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to dataupdater 176, object updater 177, and GUI updater 178. In someembodiments, data updater 176, object updater 177, and GUI updater 178are included in a single module of a respective application 136-1 orapplication view 191. In other embodiments, they are included in two ormore software modules.

It shall be understood that the foregoing discussion regarding eventhandling of user touches on touch-sensitive displays also applies toother forms of user inputs to operate multifunction devices 100 withinput devices, not all of which are initiated on touch screens. Forexample, mouse movement and mouse button presses, optionally coordinatedwith single or multiple keyboard presses or holds; contact movementssuch as taps, drags, scrolls, etc. on touchpads; pen stylus inputs;movement of the device; oral instructions; detected eye movements;biometric inputs; and/or any combination thereof are optionally utilizedas inputs corresponding to sub-events which define an event to berecognized.

FIG. 2 illustrates a portable multifunction device 100 having a touchscreen 112 in accordance with some embodiments. The touch screenoptionally displays one or more graphics within user interface (UI) 200.In this embodiment, as well as others described below, a user is enabledto select one or more of the graphics by making a gesture on thegraphics, for example, with one or more fingers 202 (not drawn to scalein the figure) or one or more styluses 203 (not drawn to scale in thefigure). In some embodiments, selection of one or more graphics occurswhen the user breaks contact with the one or more graphics. In someembodiments, the gesture optionally includes one or more taps, one ormore swipes (from left to right, right to left, upward and/or downward),and/or a rolling of a finger (from right to left, left to right, upwardand/or downward) that has made contact with device 100. In someimplementations or circumstances, inadvertent contact with a graphicdoes not select the graphic. For example, a swipe gesture that sweepsover an application icon optionally does not select the correspondingapplication when the gesture corresponding to selection is a tap.

Device 100 optionally also include one or more physical buttons, such as“home” or menu button 204. As described previously, menu button 204 is,optionally, used to navigate to any application 136 in a set ofapplications that are, optionally, executed on device 100.Alternatively, in some embodiments, the menu button is implemented as asoft key in a GUI displayed on touch screen 112.

In some embodiments, device 100 includes touch screen 112, menu button204, push button 206 for powering the device on/off and locking thedevice, volume adjustment button(s) 208, subscriber identity module(SIM) card slot 210, headset jack 212, and docking/charging externalport 124. Push button 206 is, optionally, used to turn the power on/offon the device by depressing the button and holding the button in thedepressed state for a predefined time interval; to lock the device bydepressing the button and releasing the button before the predefinedtime interval has elapsed; and/or to unlock the device or initiate anunlock process. In an alternative embodiment, device 100 also acceptsverbal input for activation or deactivation of some functions throughmicrophone 113. Device 100 also, optionally, includes one or morecontact intensity sensors 165 for detecting intensity of contacts ontouch screen 112 and/or one or more tactile output generators 167 forgenerating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with adisplay and a touch-sensitive surface in accordance with someembodiments. Device 300 need not be portable. In some embodiments,device 300 is a laptop computer, a desktop computer, a tablet computer,a multimedia player device, a navigation device, an educational device(such as a child's learning toy), a gaming system, or a control device(e.g., a home or industrial controller). Device 300 typically includesone or more processing units (CPUs) 310, one or more network or othercommunications interfaces 360, memory 370, and one or more communicationbuses 320 for interconnecting these components. Communication buses 320optionally include circuitry (sometimes called a chipset) thatinterconnects and controls communications between system components.Device 300 includes input/output (I/O) interface 330 comprising display340, which is typically a touch screen display. I/O interface 330 alsooptionally includes a keyboard and/or mouse (or other pointing device)350 and touchpad 355, tactile output generator 357 for generatingtactile outputs on device 300 (e.g., similar to tactile outputgenerator(s) 167 described above with reference to FIG. 1A), sensors 359(e.g., optical, acceleration, proximity, touch-sensitive, and/or contactintensity sensors similar to contact intensity sensor(s) 165 describedabove with reference to FIG. 1A).

Memory 370 optionally includes one or more storage devicesremotely located from CPU(s) 310. In some embodiments, memory 370 storesprograms, modules, and data structures analogous to the programs,modules, and data structures stored in memory 102 of portablemultifunction device 100 (FIG. 1A), or a subset thereof. Furthermore,memory 370 optionally stores additional programs, modules, and datastructures not present in memory 102 of portable multifunction device100. For example, memory 370 of device 300 optionally stores drawingmodule 380, presentation module 382, word processing module 384, websitecreation module 386, disk authoring module 388, and/or spreadsheetmodule 390, while memory 102 of portable multifunction device 100 (FIG.1A) optionally does not store these modules.

Each of the above-identified elements in FIG. 3 is, optionally, storedin one or more of the previously mentioned memory devices. Each of theabove-identified modules corresponds to a set of instructions forperforming a function described above. The above-identified modules orprograms (e.g., sets of instructions) need not be implemented asseparate software programs, procedures, or modules, and thus varioussubsets of these modules are, optionally, combined or otherwiserearranged in various embodiments. In some embodiments, memory 370optionally stores a subset of the modules and data structures identifiedabove. Furthermore, memory 370 optionally stores additional modules anddata structures not described above.

Attention is now directed towards embodiments of user interfaces thatare, optionally, implemented on, for example, portable multifunctiondevice 100.

FIG. 4A illustrates an exemplary user interface for a menu ofapplications on portable multifunction device 100 in accordance withsome embodiments. Similar user interfaces are, optionally, implementedon device 300. In some embodiments, user interface 400 includes thefollowing elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),        such as cellular and Wi-Fi signals;    -   Time 404;    -   Bluetooth indicator 405;    -   Battery status indicator 406;    -   Tray 408 with icons for frequently used applications, such as:        -   Icon 416 for telephone module 138, labeled “Phone,” which            optionally includes an indicator 414 of the number of missed            calls or voicemail messages;        -   Icon 418 for e-mail client module 140, labeled “Mail,” which            optionally includes an indicator 410 of the number of unread            e-mails;        -   Icon 420 for browser module 147, labeled “Browser;” and        -   Icon 422 for video and music player module 152, also            referred to as iPod (trademark of Apple Inc.) module 152,            labeled “iPod;” and    -   Icons for other applications, such as:        -   Icon 424 for IM module 141, labeled “Messages;”        -   Icon 426 for calendar module 148, labeled “Calendar;”        -   Icon 428 for image management module 144, labeled “Photos;”        -   Icon 430 for camera module 143, labeled “Camera;”        -   Icon 432 for online video module 155, labeled “Online            Video;”        -   Icon 434 for stocks widget 149-2, labeled “Stocks;”        -   Icon 436 for map module 154, labeled “Maps;”        -   Icon 438 for weather widget 149-1, labeled “Weather;”        -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”        -   Icon 442 for workout support module 142, labeled “Workout            Support;”        -   Icon 444 for notes module 153, labeled “Notes;” and        -   Icon 446 for a settings application or module, labeled            “Settings,” which provides access to settings for device 100            and its various applications 136.

It should be noted that the icon labels illustrated in FIG. 4A aremerely exemplary. For example, icon 422 for video and music playermodule 152 is labeled “Music” or “Music Player.” Other labels are,optionally, used for various application icons. In some embodiments, alabel for a respective application icon includes a name of anapplication corresponding to the respective application icon. In someembodiments, a label for a particular application icon is distinct froma name of an application corresponding to the particular applicationicon.

FIG. 4B illustrates an exemplary user interface on a device (e.g.,device 300, FIG. 3 ) with a touch-sensitive surface 451 (e.g., a tabletor touchpad 355, FIG. 3 ) that is separate from the display 450 (e.g.,touch screen display 112). Device 300 also, optionally, includes one ormore contact intensity sensors (e.g., one or more of sensors 359) fordetecting intensity of contacts on touch-sensitive surface 451 and/orone or more tactile output generators 357 for generating tactile outputsfor a user of device 300.

Although some of the examples that follow will be given with referenceto inputs on touch screen display 112 (where the touch-sensitive surfaceand the display are combined), in some embodiments, the device detectsinputs on a touch-sensitive surface that is separate from the display,as shown in FIG. 4B. In some embodiments, the touch-sensitive surface(e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) thatcorresponds to a primary axis (e.g., 453 in FIG. 4B) on the display(e.g., 450). In accordance with these embodiments, the device detectscontacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface451 at locations that correspond to respective locations on the display(e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470).In this way, user inputs (e.g., contacts 460 and 462, and movementsthereof) detected by the device on the touch-sensitive surface (e.g.,451 in FIG. 4B) are used by the device to manipulate the user interfaceon the display (e.g., 450 in FIG. 4B) of the multifunction device whenthe touch-sensitive surface is separate from the display. It should beunderstood that similar methods are, optionally, used for other userinterfaces described herein.

Additionally, while the following examples are given primarily withreference to finger inputs (e.g., finger contacts, finger tap gestures,finger swipe gestures), it should be understood that, in someembodiments, one or more of the finger inputs are replaced with inputfrom another input device (e.g., a mouse-based input or stylus input).For example, a swipe gesture is, optionally, replaced with a mouse click(e.g., instead of a contact) followed by movement of the cursor alongthe path of the swipe (e.g., instead of movement of the contact). Asanother example, a tap gesture is, optionally, replaced with a mouseclick while the cursor is located over the location of the tap gesture(e.g., instead of detection of the contact followed by ceasing to detectthe contact). Similarly, when multiple user inputs are simultaneouslydetected, it should be understood that multiple computer mice are,optionally, used simultaneously, or a mouse and finger contacts are,optionally, used simultaneously.

FIG. 5A illustrates exemplary personal electronic device 500. Device 500includes body 502. In some embodiments, device 500 can include some orall of the features described with respect to devices 100 and 300 (e.g.,FIGS. 1A-4B). In some embodiments, device 500 has touch-sensitivedisplay screen 504, hereafter touch screen 504. Alternatively, or inaddition to touch screen 504, device 500 has a display and atouch-sensitive surface. As with devices 100 and 300, in someembodiments, touch screen 504 (or the touch-sensitive surface)optionally includes one or more intensity sensors for detectingintensity of contacts (e.g., touches) being applied. The one or moreintensity sensors of touch screen 504 (or the touch-sensitive surface)can provide output data that represents the intensity of touches. Theuser interface of device 500 can respond to touches based on theirintensity, meaning that touches of different intensities can invokedifferent user interface operations on device 500.

Exemplary techniques for detecting and processing touch intensity arefound, for example, in related applications: International PatentApplication Serial No. PCT/US2013/040061, titled “Device, Method, andGraphical User Interface for Displaying User Interface ObjectsCorresponding to an Application,” filed May 8, 2013, published as WIPOPublication No. WO/2013/169849, and International Patent ApplicationSerial No. PCT/US2013/069483, titled “Device, Method, and Graphical UserInterface for Transitioning Between Touch Input to Display OutputRelationships,” filed Nov. 11, 2013, published as WIPO Publication No.WO/2014/105276, each of which is hereby incorporated by reference intheir entirety.

In some embodiments, device 500 has one or more input mechanisms 506 and508. Input mechanisms 506 and 508, if included, can be physical.Examples of physical input mechanisms include push buttons and rotatablemechanisms. In some embodiments, device 500 has one or more attachmentmechanisms. Such attachment mechanisms, if included, can permitattachment of device 500 with, for example, hats, eyewear, earrings,necklaces, shirts, jackets, bracelets, watch straps, chains, trousers,belts, shoes, purses, backpacks, and so forth. These attachmentmechanisms permit device 500 to be worn by a user.

FIG. 5B depicts exemplary personal electronic device 500. In someembodiments, device 500 can include some or all of the componentsdescribed with respect to FIGS. 1A, 1B, and 3. Device 500 has bus 512that operatively couples I/O section 514 with one or more computerprocessors 516 and memory 518. I/O section 514 can be connected todisplay 504, which can have touch-sensitive component 522 and,optionally, intensity sensor 524 (e.g., contact intensity sensor). Inaddition, I/O section 514 can be connected with communication unit 530for receiving application and operating system data, using Wi-Fi,Bluetooth, near field communication (NFC), cellular, and/or otherwireless communication techniques. Device 500 can include inputmechanisms 506 and/or 508. Input mechanism 506 is, optionally, arotatable input device or a depressible and rotatable input device, forexample. Input mechanism 508 is, optionally, a button, in some examples.

Input mechanism 508 is, optionally, a microphone, in some examples.Personal electronic device 500 optionally includes various sensors, suchas GPS sensor 532, accelerometer 534, directional sensor 540 (e.g.,compass), gyroscope 536, motion sensor 538, and/or a combinationthereof, all of which can be operatively connected to I/O section 514.

Memory 518 of personal electronic device 500 can include one or morenon-transitory computer-readable storage mediums, for storingcomputer-executable instructions, which, when executed by one or morecomputer processors 516, for example, can cause the computer processorsto perform the techniques described below, including processes 1200-1700(FIGS. 12A-17B). A computer-readable storage medium can be any mediumthat can tangibly contain or store computer-executable instructions foruse by or in connection with the instruction execution system,apparatus, or device. In some examples, the storage medium is atransitory computer-readable storage medium. In some examples, thestorage medium is a non-transitory computer-readable storage medium. Thenon-transitory computer-readable storage medium can include, but is notlimited to, magnetic, optical, and/or semiconductor storages. Examplesof such storage include magnetic disks, optical discs based on CD, DVD,or Blu-ray technologies, as well as persistent solid-state memory suchas flash, solid-state drives, and the like. Personal electronic device500 is not limited to the components and configuration of FIG. 5B, butcan include other or additional components in multiple configurations.

As used here, the term “affordance” refers to a user-interactivegraphical user interface object that is, optionally, displayed on thedisplay screen of devices 100, 300, and/or 500 (FIGS. 1A, 3, and 5A-5B).For example, an image (e.g., icon), a button, and text (e.g., hyperlink)each optionally constitute an affordance.

As used herein, the term “focus selector” refers to an input elementthat indicates a current part of a user interface with which a user isinteracting. In some implementations that include a cursor or otherlocation marker, the cursor acts as a “focus selector” so that when aninput (e.g., a press input) is detected on a touch-sensitive surface(e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B)while the cursor is over a particular user interface element (e.g., abutton, window, slider, or other user interface element), the particularuser interface element is adjusted in accordance with the detectedinput. In some implementations that include a touch screen display(e.g., touch-sensitive display system 112 in FIG. 1A or touch screen 112in FIG. 4A) that enables direct interaction with user interface elementson the touch screen display, a detected contact on the touch screen actsas a “focus selector” so that when an input (e.g., a press input by thecontact) is detected on the touch screen display at a location of aparticular user interface element (e.g., a button, window, slider, orother user interface element), the particular user interface element isadjusted in accordance with the detected input. In some implementations,focus is moved from one region of a user interface to another region ofthe user interface without corresponding movement of a cursor ormovement of a contact on a touch screen display (e.g., by using a tabkey or arrow keys to move focus from one button to another button); inthese implementations, the focus selector moves in accordance withmovement of focus between different regions of the user interface.Without regard to the specific form taken by the focus selector, thefocus selector is generally the user interface element (or contact on atouch screen display) that is controlled by the user so as tocommunicate the user's intended interaction with the user interface(e.g., by indicating, to the device, the element of the user interfacewith which the user is intending to interact). For example, the locationof a focus selector (e.g., a cursor, a contact, or a selection box) overa respective button while a press input is detected on thetouch-sensitive surface (e.g., a touchpad or touch screen) will indicatethat the user is intending to activate the respective button (as opposedto other user interface elements shown on a display of the device).

As used in the specification and claims, the term “characteristicintensity” of a contact refers to a characteristic of the contact basedon one or more intensities of the contact. In some embodiments, thecharacteristic intensity is based on multiple intensity samples. Thecharacteristic intensity is, optionally, based on a predefined number ofintensity samples, or a set of intensity samples collected during apredetermined time period (e.g., 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10seconds) relative to a predefined event (e.g., after detecting thecontact, prior to detecting liftoff of the contact, before or afterdetecting a start of movement of the contact, prior to detecting an endof the contact, before or after detecting an increase in intensity ofthe contact, and/or before or after detecting a decrease in intensity ofthe contact). A characteristic intensity of a contact is, optionally,based on one or more of: a maximum value of the intensities of thecontact, a mean value of the intensities of the contact, an averagevalue of the intensities of the contact, a top 10 percentile value ofthe intensities of the contact, a value at the half maximum of theintensities of the contact, a value at the 90 percent maximum of theintensities of the contact, or the like. In some embodiments, theduration of the contact is used in determining the characteristicintensity (e.g., when the characteristic intensity is an average of theintensity of the contact over time). In some embodiments, thecharacteristic intensity is compared to a set of one or more intensitythresholds to determine whether an operation has been performed by auser. For example, the set of one or more intensity thresholdsoptionally includes a first intensity threshold and a second intensitythreshold. In this example, a contact with a characteristic intensitythat does not exceed the first threshold results in a first operation, acontact with a characteristic intensity that exceeds the first intensitythreshold and does not exceed the second intensity threshold results ina second operation, and a contact with a characteristic intensity thatexceeds the second threshold results in a third operation. In someembodiments, a comparison between the characteristic intensity and oneor more thresholds is used to determine whether or not to perform one ormore operations (e.g., whether to perform a respective operation orforgo performing the respective operation), rather than being used todetermine whether to perform a first operation or a second operation.

In some embodiments, a portion of a gesture is identified for purposesof determining a characteristic intensity. For example, atouch-sensitive surface optionally receives a continuous swipe contacttransitioning from a start location and reaching an end location, atwhich point the intensity of the contact increases. In this example, thecharacteristic intensity of the contact at the end location is,optionally, based on only a portion of the continuous swipe contact, andnot the entire swipe contact (e.g., only the portion of the swipecontact at the end location). In some embodiments, a smoothing algorithmis, optionally, applied to the intensities of the swipe contact prior todetermining the characteristic intensity of the contact. For example,the smoothing algorithm optionally includes one or more of: anunweighted sliding-average smoothing algorithm, a triangular smoothingalgorithm, a median filter smoothing algorithm, and/or an exponentialsmoothing algorithm. In some circumstances, these smoothing algorithmseliminate narrow spikes or dips in the intensities of the swipe contactfor purposes of determining a characteristic intensity.

The intensity of a contact on the touch-sensitive surface is,optionally, characterized relative to one or more intensity thresholds,such as a contact-detection intensity threshold, a light press intensitythreshold, a deep press intensity threshold, and/or one or more otherintensity thresholds. In some embodiments, the light press intensitythreshold corresponds to an intensity at which the device will performoperations typically associated with clicking a button of a physicalmouse or a trackpad. In some embodiments, the deep press intensitythreshold corresponds to an intensity at which the device will performoperations that are different from operations typically associated withclicking a button of a physical mouse or a trackpad. In someembodiments, when a contact is detected with a characteristic intensitybelow the light press intensity threshold (e.g., and above a nominalcontact-detection intensity threshold below which the contact is nolonger detected), the device will move a focus selector in accordancewith movement of the contact on the touch-sensitive surface withoutperforming an operation associated with the light press intensitythreshold or the deep press intensity threshold. Generally, unlessotherwise stated, these intensity thresholds are consistent betweendifferent sets of user interface figures.

An increase of characteristic intensity of the contact from an intensitybelow the light press intensity threshold to an intensity between thelight press intensity threshold and the deep press intensity thresholdis sometimes referred to as a “light press” input. An increase ofcharacteristic intensity of the contact from an intensity below the deeppress intensity threshold to an intensity above the deep press intensitythreshold is sometimes referred to as a “deep press” input. An increaseof characteristic intensity of the contact from an intensity below thecontact-detection intensity threshold to an intensity between thecontact-detection intensity threshold and the light press intensitythreshold is sometimes referred to as detecting the contact on thetouch-surface. A decrease of characteristic intensity of the contactfrom an intensity above the contact-detection intensity threshold to anintensity below the contact-detection intensity threshold is sometimesreferred to as detecting liftoff of the contact from the touch-surface.In some embodiments, the contact-detection intensity threshold is zero.In some embodiments, the contact-detection intensity threshold isgreater than zero.

In some embodiments described herein, one or more operations areperformed in response to detecting a gesture that includes a respectivepress input or in response to detecting the respective press inputperformed with a respective contact (or a plurality of contacts), wherethe respective press input is detected based at least in part ondetecting an increase in intensity of the contact (or plurality ofcontacts) above a press-input intensity threshold. In some embodiments,the respective operation is performed in response to detecting theincrease in intensity of the respective contact above the press-inputintensity threshold (e.g., a “down stroke” of the respective pressinput). In some embodiments, the press input includes an increase inintensity of the respective contact above the press-input intensitythreshold and a subsequent decrease in intensity of the contact belowthe press-input intensity threshold, and the respective operation isperformed in response to detecting the subsequent decrease in intensityof the respective contact below the press-input threshold (e.g., an “upstroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoidaccidental inputs sometimes termed “jitter,” where the device defines orselects a hysteresis intensity threshold with a predefined relationshipto the press-input intensity threshold (e.g., the hysteresis intensitythreshold is X intensity units lower than the press-input intensitythreshold or the hysteresis intensity threshold is 75%, 90%, or somereasonable proportion of the press-input intensity threshold). Thus, insome embodiments, the press input includes an increase in intensity ofthe respective contact above the press-input intensity threshold and asubsequent decrease in intensity of the contact below the hysteresisintensity threshold that corresponds to the press-input intensitythreshold, and the respective operation is performed in response todetecting the subsequent decrease in intensity of the respective contactbelow the hysteresis intensity threshold (e.g., an “up stroke” of therespective press input). Similarly, in some embodiments, the press inputis detected only when the device detects an increase in intensity of thecontact from an intensity at or below the hysteresis intensity thresholdto an intensity at or above the press-input intensity threshold and,optionally, a subsequent decrease in intensity of the contact to anintensity at or below the hysteresis intensity, and the respectiveoperation is performed in response to detecting the press input (e.g.,the increase in intensity of the contact or the decrease in intensity ofthe contact, depending on the circumstances).

For ease of explanation, the descriptions of operations performed inresponse to a press input associated with a press-input intensitythreshold or in response to a gesture including the press input are,optionally, triggered in response to detecting either: an increase inintensity of a contact above the press-input intensity threshold, anincrease in intensity of a contact from an intensity below thehysteresis intensity threshold to an intensity above the press-inputintensity threshold, a decrease in intensity of the contact below thepress-input intensity threshold, and/or a decrease in intensity of thecontact below the hysteresis intensity threshold corresponding to thepress-input intensity threshold. Additionally, in examples where anoperation is described as being performed in response to detecting adecrease in intensity of a contact below the press-input intensitythreshold, the operation is, optionally, performed in response todetecting a decrease in intensity of the contact below a hysteresisintensity threshold corresponding to, and lower than, the press-inputintensity threshold.

Attention is now directed towards embodiments of user interfaces (“UI”)and associated processes that are implemented on an electronic device,such as portable multifunction device 100, device 300, or device 500.

FIGS. 6A-6S illustrate exemplary user interfaces for interacting with anelectronic device without touching a display screen or other physicalinput mechanism, in accordance with some embodiments. The userinterfaces in these figures are used to illustrate the processesdescribed below, including the processes in FIGS. 12A-12B.

In particular, FIGS. 6A-6S illustrate exemplary user interfaces forresponding to an incoming telephone call with an electronic device 500.The electronic device 500 includes a display screen 504 and a tiltsensor, among other elements which can be found above and/or asdiscussed in reference to FIG. 5A. The display screen 504 can be atouch-sensitive display screen, and the tilt sensor can be anaccelerometer 534, directional sensor 540 (e.g., compass), gyroscope536, motion sensor 538, and/or a combination thereof. In the presentexample, device 500 is a wearable device on a user's wrist, such as asmart watch.

As shown in FIG. 6A, an incoming call notification 602 is initiallydisplayed when the incoming telephone call is received. In addition, ananswer call affordance 604 and a decline call affordance 606 aredisplayed. Throughout the sequence of interactions shown in FIGS. 6A-6G,the answer call affordance 604 or the decline call affordance 606 can betouched by the user to perform their respective operations with theelectronic device 500 (e.g., answering the incoming call or decliningthe incoming telephone call, respectively). As shown in FIG. 6A,electronic device 500 is worn on the user's left wrist and is being heldin a position such that display screen 504 is directly visible to theuser's eyes (while being substantially perpendicular to the ground),such as is typical for users when they are checking the time.

As shown in FIG. 6B, the incoming call notification 602 is replaced withan incoming call track 608. In some embodiments, the incoming call track608 is displayed a predetermined time after initially receiving theincoming telephone call and/or in response to a user action. Forinstance, in some embodiments, the incoming call track 608 is displayedin response to the user lifting their arm into a raised position wherethe display screen 504 is visible to the user. The incoming call track608 includes a right track segment 610 and a left track segment 612. Theright and left track segments 610 and 612 share a center segment of theincoming call track 608. A graphical object 614 is displayed at aninitial location on the center segment of the incoming call track 608.In some embodiments, the graphical object 614 is a virtualrepresentation of a physical object (e.g., a ball). From the sharedcenter segment of the incoming call track 608, the right track segment610 leads to the answer call affordance 604, and the left track segment612 leads to the decline call affordance 606. A first demarcation 616 isdisplayed at the end of the right track segment 610 proximate to theanswer call affordance 604, and a second demarcation 618 is displayed atthe end of the left track segment 612 proximate to the decline callaffordance 606.

As shown in FIG. 6C, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist away from theirbody (e.g., the electronic device 500 is tilted up such that the bottomof the display screen 504 is moved upward relative to the top of thedisplay screen 504). In response to this change in orientation of theelectronic device 500, the graphical object 614 moves along the centersegment of the incoming call track 608 toward the top of the displayscreen 504. In some embodiments, the movement of the graphical object614 between the different locations shown in FIGS. 6B-6G is animated.The animation corresponds to a simulated physical movement of thegraphical object 614 rolling along the incoming call track 608. Forinstance, in some embodiments, the acceleration and velocity of thegraphical object 614 as it moves along the incoming call track 608 isrepresentative of how a physical ball would roll along a physical trackbeing held in the same orientation as the electronic device 500.

While the graphical object 614 is displayed at the location shown inFIG. 6C, if the user rotates their wrist back toward their body (e.g.,the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504), then the graphical object 614 moves back toward its initiallocation on the center segment of the incoming call track 608 as shownin FIG. 6B. Alternatively, in some embodiments, the graphical object 614remains at the furthest location it reached in the center segment of theincoming call track 608, such as shown in FIG. 6C (e.g., the graphicalobject 614 does not lose progress along the incoming call track 608).Furthermore, while the graphical object 614 is displayed at the locationshown in FIG. 6C, if the user maintains the same orientation of theelectronic device 500 or further rotates their wrist away from theirbody (e.g., the electronic device 500 is tilted up further such that thebottom of the display screen 504 is further moved upward relative to thetop of the display screen 504), then the graphical object 614 continuesto move toward the top of the display screen 504. In some embodiments,other orientations of the electronic device 500 (e.g., tilting to theleft or right) do not have an effect on the movement of the graphicalobject 614.

As shown in FIG. 6D, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristaway from their body (e.g., the electronic device 500 is tilted upfurther such that the bottom of the display screen 504 is further movedupward relative to the top of the display screen 504). In response tothis orientation of the electronic device 500, the graphical object 614continues to move toward the top of the display screen 504 until itencounters an upper edge of the incoming call track 608. From this upperedge location, the graphical object 614 cannot continue along theincoming call track 608 without the orientation of the electronic device500 being changed to a different orientation (e.g., tilted to the left,right, or down).

While the graphical object 614 is displayed at the location shown inFIG. 6D, if the user rotates their wrist back toward their body (e.g.,the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504), then the graphical object 614 moves back toward its initiallocation on the center segment of the incoming call track 608 as shownin FIG. 6B. Alternatively, in some embodiments, the graphical object 614remains at the upper edge of the incoming call track 608, as shown inFIG. 6D (e.g., the graphical object 614 does not lose progress along theincoming call track 608). Furthermore, while the graphical object 614 isdisplayed at the location shown in FIG. 6D, if the user then changes theangle of their arm/hand to tilt the electronic device 500 to the right(e.g., the left side of the display screen 504 is moved upward relativeto the right side of the display screen 504), then the graphical objectmoves toward the right side of the display screen 504 along right tracksegment 610. In addition, if the user then changes the angle of theirarm/hand to tilt the electronic device 500 to the left (e.g., the rightside of the display screen 504 is moved upward relative to the left sideof the display screen 504), then the graphical object moves toward theleft side of the display screen 504 along left track segment 612. Insome embodiments, other orientations of the electronic device 500 (e.g.,tilting further up) do not have an effect on the movement of thegraphical object 614.

As shown in FIG. 6E, after the user rotates their wrist away from theirbody, the electronic device 500 is tilted to the right (e.g., the leftside of the display screen 504 is moved upward relative to the rightside of the display screen 504) as a result of the user changing theangle of their arm/hand. In response to this orientation of theelectronic device 500, the graphical object 614 moves toward the rightside of the display screen 504 along right track segment 610, until thegraphical object 614 encounters a right edge of the right track segment610. From this right edge location, the graphical object 614 cannotcontinue along the right track segment 610 without the orientation ofthe electronic device 500 being changed to a different orientation(e.g., tilted to the left or down).

While the graphical object 614 is displayed at the location shown inFIG. 6E, if the user changes the angle of their arm/hand to tilt theelectronic device 500 to the left (e.g., the right side of the displayscreen 504 is moved upward relative to the left side of the displayscreen 504), then the graphical object 614 moves back along the upperedge of the incoming call track 608 as shown in FIG. 6D. Alternatively,in some embodiments, the graphical object 614 remains at the right edgeof the right track segment 610, as shown in FIG. 6E (e.g., the graphicalobject 614 does not lose progress along the incoming call track 608).Furthermore, while the graphical object 614 is displayed at the locationshown in FIG. 6E, if the user then rotates their wrist toward their body(e.g., the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504), then the graphical object 614 moves down the right tracksegment 610 toward the bottom of the display screen 504. In someembodiments, other orientations of the electronic device 500 (e.g.,tilting further up or further to the right) do not have an effect on themovement of the graphical object 614.

As shown in FIG. 6F, after tilting the electronic device 500 to theright, the orientation of the electronic device 500 is further changedas a result of the user rotating their wrist toward their body (e.g.,the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504). In response to this orientation of the electronic device500, the graphical object 614 moves down the right track segment 610toward the bottom of the display screen 504.

While the graphical object 614 is displayed at the location shown inFIG. 6F, if the user then rotates their wrist away from their body(e.g., the electronic device 500 is tilted up such that the bottom ofthe display screen 504 is moved upward relative to the top of thedisplay screen 504), then the graphical object 614 moves back toward theupper edge of the incoming call track 608, as shown in FIG. 6E.Alternatively, in some embodiments, the graphical object 614 remains atthe furthest location it reached in the right track segment 612, asshown in FIG. 6F (e.g., the graphical object 614 does not lose progressalong the incoming call track 608). Furthermore, while the graphicalobject 614 is displayed at the location shown in FIG. 6F, if the usermaintains the same orientation of the electronic device 500 or furtherrotates their wrist toward their body (e.g., the electronic device 500is tilted down further such that the top of the display screen 504 isfurther moved upward relative to the bottom of the display screen 504),then the graphical object 614 continues to move down the right tracksegment 610 toward the bottom of the display screen 504. In someembodiments, other orientations of the electronic device 500 (e.g.,tilting to the left or right) do not have an effect on the movement ofthe graphical object 614.

As shown in FIG. 6G, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristtoward their body. In response to this orientation of the electronicdevice 500, the graphical object 614 continues to move toward the bottomof the display screen 504 until it reaches the first demarcation 616 atthe end of the right track segment 610. The graphical object 614 thenstops moving and is displayed at the end of the right track segment 610proximate to the answer call affordance 604. In some embodiments, theend of the right track segment 610 intersects the answer call affordance604. In these embodiments, the graphical object 614 can be displayedadjacent to the answer call affordance 604, on top of the answer callaffordance 604, behind the answer call affordance 604, or at otherpositions proximate to the answer call affordance 604.

In response to the graphical element 614 being displayed at the end ofthe right track segment 610 proximate to the answer call affordance 604,a call answering notification 620 is initiated, as shown in FIG. 6H. Thecall answering notification 620 is an animated graphic that starts as asmall circle proximate to the end of the right track segment 610 thatthen expands toward the center of the display screen 504 until itreaches a full-size. The full-size call answering notification 620 isshown in FIG. 6I. The call answering notification 620 indicates to theuser that an answer call operation has been initiated by electronicdevice 500. In addition, in some embodiments, once the full-size callanswering notification 620 is displayed, the answer call affordance 604changes visual appearance to further indicate to the user that theanswer call operation has been initiated. The answer call operationinstructs the electronic device 500 or other associated device to answerthe incoming telephone call.

A different sequence of interactions, related to those described inreference to FIGS. 6E-6I, can be carried out to decline an incomingtelephone call with the electronic device 500. Instead of tilting theelectronic device 500 to the right as shown in FIG. 6E, the electronicdevice is tilted to the left (e.g., the right side of the display screen504 is moved upward relative to the left side of the display screen504). In response to this orientation of the electronic device 500, thegraphical object 614 moves toward the left side of the display screen504 along left track segment 612, until the graphical object 614encounters a left edge of the left track segment 612. The user thenrotates their wrist toward their body (similar to as shown in FIGS.6F-6G) to move the graphical object 614 down the left track segment 612toward the bottom of the display screen 504. The graphical object 614continues to move toward the bottom of the display screen 504 until itreaches the second demarcation 618 at the end of the left track segment612. The graphical object 614 then stops moving and is displayed at theend of the left track segment 612 proximate to the decline callaffordance 606. In some embodiments, the end of the left track segment612 intersects the decline call affordance 606. In these embodiments,the graphical object 614 can be displayed adjacent to the decline callaffordance 606, on top of the decline call affordance 606, behind thedecline call affordance 606, or at other positions proximate to thedecline call affordance 606.

In response to the graphical element 614 being displayed at the end ofthe left track segment 612 proximate to the decline call affordance 606,a call ending notification is initiated (similar to the call endingnotification 630 shown in FIG. 6Q). The call ending notification is ananimated graphic that starts as a small circle proximate to the end ofthe left track segment 612 that then expands toward the center of thedisplay screen 504 until it reaches a full-size. The call endingnotification indicates to the user that a decline call operation hasbeen initiated by electronic device 500. The decline call operationinstructs the electronic device 500 or other associated device todecline the incoming telephone call.

Once in an active telephone call, the incoming call track 608 isreplaced with an end call track 622 on the display screen 504, as shownin FIG. 6J. In addition, the answer call affordance 604 is replaced witha mute affordance 624. The decline call affordance 606 remains in thesame location on the display screen as in FIGS. 6A-6I. Throughout thesequence of interactions shown in FIGS. 6J-6P, the decline callaffordance 606 or mute affordance 624 can be touched by the user toperform their respective operation with the electronic device 500 (e.g.,end the active telephone call or mute the microphone, respectively).

The graphical object 614 is displayed in the same location on thedisplay screen 504 as in FIGS. 6G-6I (e.g., at the end of what wasformerly the right track segment 610 of the incoming call track 608).The end call track 608 leads from this current location of the graphicalobject 614 to the decline call affordance 606 (e.g., from the end ofwhat was formerly the right track segment 610 to the decline callaffordance 606). A third demarcation 628 is displayed at the end of theend call track 622 proximate to the decline call affordance 606. In someembodiments, a call timer 626 is also displayed in a center region ofthe display screen 504. The time shown in the call timer 626 increasesto indicate how long the telephone call is active, as shown in FIG. 6K.

As shown in FIG. 6L, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist away from theirbody. In response to the new orientation of the electronic device 500,the graphical object 614 moves along the end call track 622 toward thetop of the display screen 504. In some embodiments, the movement of thegraphical object 614 between the different locations shown in FIGS.6J-6P is animated in a similar manner as described in reference to FIGS.6B-6G. The animation corresponds to a simulated physical movement of thegraphical object 614 rolling along the end call track 622. For instance,in some embodiments, the acceleration and velocity of the graphicalobject 614 as it moves along the end call track 622 is representative ofhow a physical ball would roll along a physical track being held in thesame orientation as the electronic device 500.

While the graphical object 614 is displayed at the location shown inFIG. 6L, if the user rotates their wrist back toward their body (e.g.,the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504), then the graphical object 614 moves back toward its initiallocation on the end call track 622 as shown in FIGS. 6J-6K.Alternatively, in some embodiments, the graphical object 614 remains atthe furthest location it reached in the end call track 622, as shown inFIG. 6L (e.g., the graphical object 614 does not lose progress along theend call track 622). Furthermore, while the graphical object 614 isdisplayed at the location shown in FIG. 6L, if the user maintains thesame orientation of the electronic device 500 or further rotates theirwrist away from their body (e.g., the electronic device 500 is tilted upfurther such that the bottom of the display screen 504 is further movedupward relative to the top of the display screen 504), then thegraphical object 614 continues to move toward the top of the displayscreen 504. In some embodiments, other orientations of the electronicdevice 500 (e.g., tilting to the left or right) do not have an effect onthe movement of the graphical object 614.

As shown in FIG. 6M, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristaway from their body. In response to this orientation of the electronicdevice 500, the graphical object 614 continues to move toward the top ofthe display screen 504 until it encounters an upper edge of the end calltrack 622. From this upper edge location, the graphical object 614cannot continue along the end call track 622 without the orientation ofthe electronic device 500 being changed to a different orientation(e.g., tilted to the left).

While the graphical object 614 is displayed at the location shown inFIG. 6M, if the user rotates their wrist back toward their body (e.g.,the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504), then the graphical object 614 moves back toward the bottomof the display screen 504. Alternatively, in some embodiments, thegraphical object 614 remains at the upper edge of the end call track608, as shown in FIG. 6M (e.g., the graphical object 614 does not loseprogress along the end call track 608). Furthermore, while the graphicalobject 614 is displayed at the location shown in FIG. 6M, if the userthen changes the angle of their arm/hand to tilt the electronic device500 to the left (e.g., the right side of the display screen 504 is movedupward relative to the left side of the display screen 504), then thegraphical object moves toward the left side of the display screen 504along end call track 622. In some embodiments, other orientations of theelectronic device 500 (e.g., tilting further up or to the right) do nothave an effect on the movement of the graphical object 614.

As shown in FIG. 6N, after the user rotates their wrist away from theirbody, the electronic device 500 is tilted to the left (e.g., the rightside of the display screen 504 is moved upward relative to the left sideof the display screen 504) as a result of the user changing the angle oftheir arm/hand. In response to this orientation of the electronic device500, the graphical object 614 moves toward the left side of the displayscreen 504 along end call track 622, until the graphical object 614encounters a left edge of the end call track 622. From this left edgelocation, the graphical object 614 cannot continue along the end calltrack 622 without the orientation of the electronic device 500 beingchanged to a different orientation (e.g., tilted to the right or down).

While the graphical object 614 is displayed at the location shown inFIG. 6N, if the user changes the angle of their arm/hand to tilt theelectronic device 500 to the right (e.g., the left side of the displayscreen 504 is moved upward relative to the right side of the displayscreen 504), then the graphical object 614 moves back toward the rightside of the display screen 504. Alternatively, in some embodiments, thegraphical object 614 remains at the left edge of the end call track 622,as shown in FIG. 6N (e.g., the graphical object 614 does not loseprogress along the end call track 622). Furthermore, while the graphicalobject 614 is displayed at the location shown in FIG. 6N, if the userthen rotates their wrist toward their body (e.g., the electronic device500 is tilted down such that the top of the display screen 504 is movedupward relative to the bottom of the display screen 504), then thegraphical object 614 moves down the end call track 622 toward the bottomof the display screen 504. In some embodiments, other orientations ofthe electronic device 500 (e.g., tilting further up or further to theleft) do not have an effect on the movement of the graphical object 614.

As shown in FIG. 6O, after tilting the electronic device 500 to theleft, the orientation of the electronic device 500 is further changed asa result of the user rotating their wrist toward their body. In responseto this orientation of the electronic device 500, the graphical object614 moves down the left side of the end call track 622 toward the bottomof the display screen 504.

While the graphical object 614 is displayed at the location shown inFIG. 6O, if the user then rotates their wrist away from their body(e.g., the electronic device 500 is tilted up such that the bottom ofthe display screen 504 is moved upward relative to the top of thedisplay screen 504), then the graphical object 614 moves back toward theupper edge of the end call track 622, as shown in FIG. 6N.Alternatively, in some embodiments, the graphical object 614 remains atthe furthest location it reached in the end call track 622, as shown inFIG. 6O (e.g., the graphical object 614 does not lose progress along theend call track 622). Furthermore, while the graphical object 614 isdisplayed at the location shown in FIG. 6O, if the user maintains thesame orientation of the electronic device 500 or further rotates theirwrist toward their body (e.g., the electronic device 500 is tilted downfurther such that the top of the display screen 504 is further movedupward relative to the bottom of the display screen 504), then thegraphical object 614 continues to move down the end call track 622toward the bottom of the display screen 504. In some embodiments, otherorientations of the electronic device 500 (e.g., tilting to the left orright) do not have an effect on the movement of the graphical object614.

As shown in FIG. 6P, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristtoward their body. In response to this orientation of the electronicdevice 500, the graphical object 614 continues to move toward the bottomof the display screen 504 until it reaches the third demarcation 628 atthe end of the end call track 622. The graphical object 614 then stopsmoving and is displayed at the end of the end call track 622 proximateto the decline call affordance 606. In some embodiments, the end of theend call track intersects the decline call affordance 606. In theseembodiments, the graphical object 614 can be displayed adjacent to thedecline call affordance 606, on top of the decline call affordance 606,behind the decline call affordance 606, or at other positions proximateto the decline call affordance 606.

In response to the graphical element 614 being displayed at the end ofthe end call track 622 proximate to the decline call affordance 606, acall ending notification 630 is initiated, as shown in FIG. 6Q. The callending notification 630 is an animated graphic that starts as a smallcircle proximate to the end of the end call track 622 that then expandstoward the center of the display screen 504 until it reaches afull-size. The full-size call ending notification 630 is shown in FIG.6R. The call ending notification 630 indicates to the user that an endcall operation has been initiated by electronic device 500. Once thefull-size call answering notification 620 is displayed, the otherelements on the display screen 504 can be removed. The end calloperation instructs the electronic device 500 or other associated deviceto end the active telephone call.

Once the active telephone call has ended, a call ended notification 632is displayed on the display screen 504, as shown in FIG. 6S.

FIGS. 7A-7Q illustrate exemplary user interfaces for interacting with anelectronic device without touching a display screen or other physicalinput mechanism, in accordance with some embodiments. The userinterfaces in these figures are used to illustrate the processesdescribed below, including the processes in FIGS. 13A-13B. As shown inFIG. 7A, electronic device 500 is worn on the user's left wrist and isbeing held in a position such that display screen 504 is directlyvisible to the user's eyes (while being substantially perpendicular tothe ground), such as is typical for users when they are checking thetime.

In particular, FIGS. 7A-7Q illustrate exemplary user interfaces forresponding to an incoming telephone call with an electronic device 500.The electronic device 500 includes a display screen 504 and a tiltsensor, among other elements which can be found above and/or asdiscussed in reference to FIG. 5A. The display screen 504 can be atouch-sensitive display screen, and the tilt sensor can be anaccelerometer 534, directional sensor 540 (e.g., compass), gyroscope536, motion sensor 538, and/or a combination thereof. In the presentexample, device 500 is a wearable device on a user's wrist, such as asmart watch.

As shown in FIG. 7A, an incoming call notification 702 is initiallydisplayed when the incoming telephone call is received. In addition, ananswer call affordance 704 and a decline call affordance 706 aredisplayed. Throughout the sequence of interactions shown in FIGS. 7A-7P,the answer call affordance 704 or the decline call affordance 706 can betouched by the user to perform their respective operations with theelectronic device 500 (e.g., answering the incoming call or decliningthe incoming telephone call, respectively).

As shown in FIGS. 7B-7E, a sequence of movement indicators 708 a-708 d(e.g., musical notes) are displayed in response to the incomingtelephone call being received. In some embodiments, the first movementindicator 708 a is displayed a predetermined time after initiallyreceiving the incoming telephone call and/or in response to a useraction. For instance, in some embodiments, the first movement indicator708 a is displayed in response to the user lifting their arm into araised position where the display screen 504 is visible to the user. Thesecond, third, and fourth movement indicators 708 b-708 d then appear insequence after the first movement indicator 708 a is displayed, wherethe second movement indicator 708 b is displayed a predetermined timeafter the first movement indicator 708 a is displayed, and so on.Alternatively, the entire sequence of movement indicators 708 a-708 dcan be displayed approximately simultaneously in response to theincoming telephone call being received. The sequence of movementindicators 708 a-708 d indicates a sequence of movements that can bemade with the electronic device 500 to respond to the incoming telephonecall. For instance, the first movement indicator 708 a (e.g., a “high”musical note) indicates that the first movement the user would make withthe electronic device 500 is to rotate the display screen 504 away fromtheir body (e.g., the user rotates their wrist to move the bottom of thedisplay screen 504 upward relative to the top of the display screen504). The second movement indicator 708 b (e.g., a “low” musical note)indicates that the second movement the user would make with theelectronic device 500 is to rotate the display screen 504 toward theirbody (e.g., the user rotates their wrist to move the top of the displayscreen 504 upward relative to the bottom of the display screen 504). Thethird and fourth movement indicators 708 c-708 d (e.g., high musicalnotes) indicate that the user would rotate the display screen 504 awayfrom their body two more times. In some embodiments, each of themovements indicated by the sequence of movement indicators 708 a-708 dalso include a rotation of the electronic device 500 back toward itsoriginal orientation within a predetermined time period (e.g., eachmovement is a “flicking” motion where the display screen 504 is quicklyrotated away/toward the user and then is immediately rotated in theopposite direction). While four movement indicators 708 a-708 d areshown in FIGS. 7B-7E, the number of movement indicators can vary. Forinstance, a sequence of two, three, or five or more movement indicatorscan be displayed in response to the incoming telephone call beingreceived. The direction of movement indicated by of the movementindicators can also vary. For instance, the sequence of movementindicators can indicate two rotations toward the user (e.g., two “low”musical notes) followed by two rotations away from the user (e.g., two“high” notes). The user can then input a sequence of movementscorresponding to each of the displayed movement indicators, such asshown in FIGS. 7G-7N.

After all of movement indicators 708 a-708 d are displayed (as shown inFIG. 7E), the movement indicators 708 a-708 d are removed from thedisplay screen 504, as shown in FIG. 7F. In some embodiments, themovement indicators 708 a-708 d are removed a predetermined time afterthe last movement indicator (e.g., 708 d) is displayed. Each of themovement indicators 708 a-708 d are then displayed again, in sequence orapproximately simultaneously, as shown in FIGS. 7B-7E. The display andremoval of the movement indicators 708 a-708 d as shown in FIGS. 7B-7Fcan repeat until a user input is received, a predetermined time periodhas elapsed, or the incoming telephone call is no longer being received.In some embodiments, the display of each of the movement indicators 708a-708 d corresponds to an audio notification of the incoming telephonecall (e.g., a “ringtone”). For instance, the audio notification caninclude a repeating sequence of four tones (e.g., one high tone, one lowtone, followed by two more high tones). In some embodiments, each of themovement indicators 708 a-708 d are displayed at approximately the sametime as each of the tones of the audio notification.

As shown in FIG. 7G, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist away from theirbody (e.g., the electronic device 500 is tilted up such that the bottomof the display screen 504 is moved upward relative to the top of thedisplay screen 504). This orientation corresponds to the movementindicated by the first movement indicator 708 a. In response to themovement of the electronic device 500 to this orientation or a similarorientation, an input indicator 710 is displayed. The input indicator710 is semi-transparent and is displayed overlapping the other elementson the display screen 504. In some embodiments, the input indicator 710is displayed when the movement of the electronic device 500 meets aminimum velocity or acceleration threshold. If the minimum velocity oracceleration threshold is not met, then the input indicator 710 is notdisplayed. In some embodiments, the input indicator 710 is an animatedgraphic that moves in the direction of movement of the electronic device504 (e.g., the input indicator 710 moves toward the top of the displayscreen 504 in response to the user rotating their wrist away from theirbody). The input indicator 710 can also be animated to enlarge in sizeduring the movement of the electronic device 504, as shown in FIG. 7H.In some embodiments, the first movement indicator 708 a is displayed inresponse to the corresponding movement of the electronic device 504 bythe user.

As shown in FIG. 7H, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristaway from their body (e.g., the electronic device 500 is tilted upfurther such that the bottom of the display screen 504 is further movedupward relative to the top of the display screen 504). The inputindicator 710 shown in FIG. 7H is displayed in an upper region of thedisplay screen to indicate to the user the direction of rotation thatwas detected by the electronic device 500. In some embodiments,following the movement of the electronic device 500 into the orientationshown in FIG. 7H or a similar orientation, the electronic device 500 isrotated back toward its original orientation (e.g., the orientationshown in FIG. 7F) within a predetermined time period (e.g., the usermakes a “flicking” motion with the electronic device 500, where thedisplay screen 504 is quickly rotated away from the user and then isimmediately rotated back toward the user).

As shown in FIG. 7I, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist toward their body(e.g., the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504). This orientation corresponds to the movement indicated bythe second movement indicator 708 b. In response to the movement of theelectronic device 500 to this orientation or a similar orientation, theinput indicator 710 is displayed. The input indicator 710 issemi-transparent and is displayed overlapping the other elements on thedisplay screen 504. In some embodiments, the input indicator 710 isdisplayed when the movement of the electronic device 500 meets a minimumvelocity or acceleration threshold. If the minimum velocity oracceleration threshold is not met, then the input indicator 710 is notdisplayed. In some embodiments, the input indicator 710 is an animatedgraphic that moves in the direction of movement of the electronic device504 (e.g., the input indicator 710 moves toward the bottom of thedisplay screen 504 in response to the user rotating their wrist towardtheir body). The input indicator 710 can also be animated to enlarge insize during the movement of the electronic device 504, as shown in FIG.7J. In some embodiments, the second movement indicator 708 b isdisplayed in response to the corresponding movement of the electronicdevice 504 by the user.

As shown in FIG. 7J, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristtoward their body (e.g., the electronic device 500 is tilted downfurther such that the top of the display screen 504 is further movedupward relative to the bottom of the display screen 504). The inputindicator 710 shown in FIG. 7J is displayed in a lower region of thedisplay screen to indicate to the user the direction of rotation thatwas detected by the electronic device 500. In some embodiments,following the movement of the electronic device 500 into the orientationshown in FIG. 7J or a similar orientation, the electronic device 500 isrotated back toward its original orientation (e.g., the orientationshown in FIG. 7F) within a predetermined time period (e.g., the usermakes a “flicking” motion with the electronic device 500, where thedisplay screen 504 is quickly rotated toward the user and then isimmediately rotated back away from the user).

As shown in FIG. 7K, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist away from theirbody a second time (e.g., the electronic device 500 is tilted up suchthat the bottom of the display screen 504 is moved upward relative tothe top of the display screen 504). This orientation corresponds to themovement indicated by the third movement indicator 708 c. In response tothe movement of the electronic device 500 to this orientation or similarorientation, the input indicator 710 is displayed. The input indicator710 is semi-transparent and is displayed overlapping the other elementson the display screen 504. In some embodiments, the input indicator 710is displayed when the movement of the electronic device 500 meets aminimum velocity or acceleration threshold. If the minimum velocity oracceleration threshold is not met, then the input indicator 710 is notdisplayed. In some embodiments, the input indicator 710 is an animatedgraphic that moves in the direction of movement of the electronic device504 (e.g., the input indicator 710 moves toward the top of the displayscreen 504 in response to the user rotating their wrist away from theirbody). The input indicator 710 can also be animated to enlarge in sizeduring the movement of the electronic device 504, as shown in FIG. 7L.In some embodiments, the third movement indicator 708 c is displayed inresponse to the corresponding movement of the electronic device 504 bythe user.

As shown in FIG. 7L, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristaway from their body the second time (e.g., the electronic device 500 istilted up further such that the bottom of the display screen 504 isfurther moved upward relative to the top of the display screen 504). Theinput indicator 710 shown in FIG. 7L is displayed in an upper region ofthe display screen to indicate to the user the direction of rotationthat was detected by the electronic device 500. In some embodiments,following the movement of the electronic device 500 into the orientationshown in FIG. 7L or a similar orientation, the electronic device 500 isrotated back toward its original orientation (e.g., the orientationshown in FIG. 7F) within a predetermined time period (e.g., the usermakes a “flicking” motion with the electronic device 500, where thedisplay screen 504 is quickly rotated away from the user and then isimmediately rotated back toward the user).

As shown in FIG. 7M, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist away from theirbody a third time (e.g., the electronic device 500 is tilted up suchthat the bottom of the display screen 504 is moved upward relative tothe top of the display screen 504). This orientation corresponds to themovement indicated by the fourth movement indicator 708 d. In responseto the movement of the electronic device 500 to this orientation or asimilar orientation, the input indicator 710 is displayed. The inputindicator 710 is semi-transparent and is displayed overlapping the otherelements on the display screen 504. In some embodiments, the inputindicator 710 is displayed when the movement of the electronic device500 meets a minimum velocity or acceleration threshold. If the minimumvelocity or acceleration threshold is not met, then the input indicator710 is not displayed. In some embodiments, the input indicator 710 is ananimated graphic that moves in the direction of movement of theelectronic device 504 (e.g., the input indicator 710 moves toward thetop of the display screen 504 in response to the user rotating theirwrist away from their body). The input indicator 710 can also beanimated to enlarge in size during the movement of the electronic device504, as shown in FIG. 7N. In some embodiments, the fourth movementindicator 708 d is displayed in response to the corresponding movementof the electronic device 504 by the user.

As shown in FIG. 7N, the orientation of the electronic device 500 isfurther changed as a result of the user further rotating their wristaway from their body the third time (e.g., the electronic device 500 istilted up further such that the bottom of the display screen 504 isfurther moved upward relative to the top of the display screen 504). Theinput indicator 710 shown in FIG. 7N is displayed in an upper region ofthe display screen to indicate to the user the direction of rotationthat was detected by the electronic device 500. In some embodiments,following the movement of the electronic device 500 into the orientationshown in FIG. 7N or similar orientation, the electronic device 500 isrotated back toward its original orientation (e.g., the orientationshown in FIG. 7F) within a predetermined time period (e.g., the usermakes a “flicking” motion with the electronic device 500, where thedisplay screen 504 is quickly rotated away from the user and then isimmediately rotated back toward the user).

In some embodiments, after the user inputs the sequence of movementscorresponding to the movement indicators 708 a-708 d, a successnotification is displayed on the display screen 504. As shown in FIGS.7O-7P, the success notification includes an animation of the movementindicators 708 a-708 d. The movement indicators 708 a-708 d enlarge insize and fade out in appearance to indicate to the user that thesequence of movements inputted by the user satisfy the sequence ofmovements indicated by the movement indicators 708 a-708 d.

In response to the user successfully performing the sequence ofmovements corresponding to the movement indicators 708 a-708 d, a callconnecting notification 712 is displayed, as shown in FIG. 7Q. The callconnecting notification 712 indicates to the user that an answer calloperation has been initiated by electronic device 500. The answer calloperation instructs the electronic device 500 or other associated deviceto answer the incoming telephone call.

If the user fails to input the sequence of movements corresponding tothe movement indicators 708 a-708 d within a predetermined time, thenthe electronic device 500 forgoes performing the operation associatedwith the movement indicators 708 a-708 d. For instance, if the user onlyinputs three out of the four movements indicated by the movementindicators 708 a-708 d within the predetermined time, then no operationwould be performed by the electronic device 500. In some embodiments,the predetermined time corresponds to a number of times the display ofthe sequence of movement indicators 708 a-708 d is repeated or an amountof time before the incoming telephone call is automatically canceled orforwarded to voicemail.

FIGS. 8A-8BI illustrate exemplary user interfaces for interacting withan electronic device without touching a display screen or other physicalinput mechanism, in accordance with some embodiments. The userinterfaces in these figures are used to illustrate the processesdescribed below, including the processes in FIG. 14 .

In particular, FIGS. 8A-8Z illustrate exemplary user interfaces forresponding to an incoming instant message with an electronic device 500.The electronic device 500 includes a display screen 504 and a tiltsensor, among other elements which can be found above and/or asdiscussed in reference to FIG. 5A. The display screen 504 can be atouch-sensitive display screen, and the tilt sensor can be anaccelerometer 534, directional sensor 540 (e.g., compass), gyroscope536, motion sensor 538, and/or a combination thereof. In the presentexample, device 500 is a wearable device on a user's wrist, such as asmart watch. As shown in FIG. 8A, electronic device 500 is worn on theuser's left wrist and is being held in a position such that displayscreen 504 is directly visible to the user's eyes (while beingsubstantially perpendicular to the ground), such as is typical for userswhen they are checking the time.

As shown in FIG. 8A, an incoming instant message 802 is displayed. Inaddition, a reply affordance 804 and dismiss affordance 806 aredisplayed. In some embodiments, the incoming instant message 802 isdisplayed a predetermined time after the instant message 802 is receivedand/or in response to a user action. For instance, in some embodiments,the instant message 802 is displayed in response to the user liftingtheir arm into a raised position where the display screen 504 is visibleto the user. Throughout the sequence of interactions shown in FIGS.8A-8E, the reply affordance 804 or the dismiss affordance 806 can betouched by the user to perform their respective operations with theelectronic device 500 (e.g., displaying a reply interface or dismissingthe incoming instant message 802, respectively).

As shown in FIG. 8B, the instant message 802 is replaced with aninstructional graphic 808 in a center region 810 of the display screen504. In some embodiments, the instructional graphic 808 is displayed apredetermined time after initially displaying the instant message 802and/or in response to a user action. For instance, in some embodiments,the instructional graphic 808 is displayed in response to the userlifting their arm into a raised position where the display screen 504 isvisible to the user. In addition, the reply affordance 804 is moved toan upper region of the display screen 504 and the dismiss affordance 806is moved to a lower region of the display screen 504. The instructionalgraphic 808 indicates movements a user can make with the electronicdevice 500 to perform the operations associated with the replyaffordance 804 and the dismiss affordance 806. In some embodiments, theinstructional graphic 808 is animated to demonstrate the movements tothe user. The movements include rotating the display screen 504 awayfrom the user's body (e.g., the user rotates their wrist to move thebottom of the display screen 504 upward relative to the top of thedisplay screen 504) or rotating the display screen 504 toward the user'sbody (e.g., the user rotates their wrist to move the top of the displayscreen 504 upward relative to the bottom of the display screen 504). Insome embodiments, each of the movements indicated by the instructionalgraphic 808 also include a rotation of the electronic device 500 backtoward its original orientation within a predetermined time period(e.g., each movement is a “flicking” motion where the display screen 504is quickly rotated away/toward the user and then is immediately rotatedin the opposite direction). The user can then input one of the movementsindicated by the instructional graphic 808, as shown in FIGS. 8C-8E andFIGS. 8X-8Z.

As shown in FIG. 8C, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist away from theirbody (e.g., the electronic device 500 is tilted up such that the bottomof the display screen 504 is moved upward relative to the top of thedisplay screen 504). This movement corresponds to one of the movementsindicated by the instructional graphic 808. In response to the movementof the electronic device 500 to this orientation or a similarorientation, an input indicator 812 is displayed. The input indicator812 is semi-transparent and is displayed overlapping the other elementson the display screen 504. In some embodiments, the input indicator 812is displayed when the movement of the electronic device 500 meets aminimum velocity or acceleration threshold. If the minimum velocity oracceleration threshold is not met, then the input indicator 812 is notdisplayed. In some embodiments, the input indicator 812 is an animatedgraphic that moves in the direction of movement of the electronic device504 (e.g., the input indicator 812 moves toward the top of the displayscreen 504 in response to the user rotating their wrist away from theirbody).

FIG. 8D illustrates the orientation of the electronic device 500 beingfurther changed as a result of the user further rotating their wristaway from their body (e.g., the electronic device 500 is tilted upfurther such that the bottom of the display screen 504 is further movedupward relative to the top of the display screen 504). The inputindicator 812 is displayed overlapping the reply affordance 804 in theupper region of the display screen 504 to indicate to the user that themovement of the electronic device 500 corresponds to a selection of thereply operation associated with the reply affordance 804. In someembodiments, following the movement of the electronic device 500 intothe orientation shown in FIG. 8D or a similar orientation, theelectronic device 500 is rotated back toward its original orientation(e.g., the orientation shown in FIG. 8B) within a predetermined timeperiod (e.g., the user makes a “flicking” motion with the electronicdevice 500, where the display screen 504 is quickly rotated away fromthe user and then is immediately rotated back toward the user).

As shown in FIG. 8E, following the rotation of the display screen 504away from the user's body as shown in FIGS. 8C-8D, the reply affordance804 and overlapping input indicator 812 move toward the center region ofthe display screen 504. The movement of the reply affordance 804 andoverlapping input indicator 812 indicates that the previous movement ofthe electronic device 500 has resulted in a selection of the replyoperation associated with the reply affordance 804.

As shown in FIG. 8F, in response to the reply affordance 804 beingselected, a list of predefined responses 814 a-814 e are displayed. Eachof the predefined responses 814 a-814 e corresponds to a message theuser can send to respond to the instant message 802 shown in FIG. 8A.For instance, the predefined responses 814 a-814 e can include “Yes,”“No,” “Maybe,” “See you there,” “Thank you,” or other common responsesto an instant message. While five predefined responses 814 a-814 e areshown in FIG. 8E, the number of predefined responses being displayed canvary. Furthermore, in some embodiments, additional predefined responsesare displayed by scrolling the list of predefined responses, asdiscussed in reference to FIGS. 8G-8O.

As shown in FIG. 8G, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist toward their body(e.g., the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504). This movement corresponds to one of the movement indicatedby the instructional graphic 808 shown in FIG. 8B. In some embodiments,following the movement of the electronic device 500 into the orientationshown in FIG. 8G or a similar orientation, the electronic device 500 isrotated back toward its original orientation (e.g., the orientationshown in FIG. 8F) within a predetermined time period (e.g., the usermakes a “flicking” motion with the electronic device 500, where thedisplay screen 504 is quickly rotated toward the user and then isimmediately rotated back away from the user).

In response to the movement of the electronic device 500 to theorientation shown in FIG. 8G or a similar orientation, the inputindicator 812 is displayed. The input indicator 812 is semi-transparentand is displayed overlapping the other elements on the display screen504. In some embodiments, the input indicator 812 is displayed when themovement of the electronic device 500 meets a minimum velocity oracceleration threshold. If the minimum velocity or accelerationthreshold is not met, then the input indicator 812 is not displayed. Insome embodiments, the input indicator 812 is an animated graphic thatmoves in the direction of movement of the electronic device 504 (e.g.,the input indicator 812 moves toward the bottom of the display screen504 in response to the user rotating their wrist toward their body). Inresponse to this movement of the electronic device 500, the predefinedresponses 814 a-814 d are scrolled down such that a predefined responsein the upper region of the display screen 504 (e.g., predefined response814 b) is moved toward the center region of the display screen 504 andthe predefined response at the bottom of the display screen 504 (e.g.,predefined response 814 e shown in FIG. 8F) is no longer displayed.

As shown in FIG. 8H, following the rotation of the display screen 504toward the user's body as shown in FIG. 8G, the predefined response 814b and input indicator 812 are displayed in the center region of thedisplay screen 504 to indicate that the list of predefined responses 814a-814 d is no longer being scrolled and the predefined responses 814a-814 d will remain in their displayed positions unless additional inputis provided by the user.

As shown in FIG. 8I, after the list of predefined responses is scrolledand the predefined response 814 b is displayed in the center region ofthe screen, predefined response 814 b is highlighted. If no additionalinput from the user is received within a predetermined time, thenpredefined response 814 b will be selected after the predetermined time.

As shown in FIG. 8J, before the predetermined time to select predefinedresponse 814 b as shown in FIG. 8I has elapsed, the orientation of theelectronic device 500 is changed as a result of the user rotating theirwrist away from their body (e.g., the electronic device 500 is tilted upsuch that the bottom of the display screen 504 is moved upward relativeto the top of the display screen 504). This movement corresponds to oneof the movement indicated by the instructional graphic 808 shown in FIG.8B. In some embodiments, following the movement of the electronic device500 into the orientation shown in FIG. 8J or a similar orientation, theelectronic device 500 is rotated back toward its original orientation(e.g., the orientation shown in FIG. 8I) within a predetermined timeperiod (e.g., the user makes a “flicking” motion with the electronicdevice 500, where the display screen 504 is quickly rotated away fromthe user and then is immediately rotated back toward from the user).

In response to the movement of the electronic device 500 to theorientation shown in FIG. 8J or a similar orientation, the inputindicator 812 is displayed. The input indicator 812 is semi-transparentand is displayed overlapping the other elements on the display screen504. In some embodiments, the input indicator 812 is displayed when themovement of the electronic device 500 meets a minimum velocity oracceleration threshold. If the minimum velocity or accelerationthreshold is not met, then the input indicator 812 is not displayed. Insome embodiments, the input indicator 812 is an animated graphic thatmoves in the direction of movement of the electronic device 504 (e.g.,the input indicator 812 moves toward the top of the display screen 504in response to the user rotating their wrist away from their body). Inresponse to this movement of the electronic device 500, the predefinedresponses 814 a-814 e are scrolled up such that a predefined response inthe lower region of the display screen 504 (e.g., predefined response814 c) is moved toward the center region of the display screen 504. As aresult of the upward scroll, the predefined response 814 e that had beenscrolled off the display screen 504 in FIGS. 8G-8I is displayed again inthe bottom region of the display screen.

As shown in FIG. 8K, following the rotation of the display screen 504away from the user's body as shown in FIG. 8J, the predefined response814 c and input indicator 812 are displayed in the center region of thedisplay screen 504 to indicate that the list of predefined responses 814a-814 e is no longer being scrolled and the predefined responses 814a-814 e will remain in their displayed positions unless additional inputis provided by the user.

As shown in FIG. 8L, after the list of predefined responses is scrolledand the predefined response 814 c is displayed in the center region ofthe screen, the predefined response 814 c is highlighted. If noadditional input from the user is received within a predetermined time,then predefined response 814 c will be selected after the predeterminedtime.

As shown in FIG. 8M, before the predetermined time to select thepredefined response 814 c as shown in FIG. 8L has elapsed, theorientation of the electronic device 500 is changed as a result of theuser rotating their wrist away from their body again (e.g., theelectronic device 500 is tilted up such that the bottom of the displayscreen 504 is moved upward relative to the top of the display screen504). This movement corresponds to one of the movement indicated by theinstructional graphic 808 shown in FIG. 8B. In some embodiments,following the movement of the electronic device 500 into the orientationshown in FIG. 8M or a similar orientation, the electronic device 500 isrotated back toward its original orientation (e.g., the orientationshown in FIG. 8L) within a predetermined time period (e.g., the usermakes a “flicking” motion with the electronic device 500, where thedisplay screen 504 is quickly rotated away from the user and then isimmediately rotated back toward from the user).

In response to the movement of the electronic device 500 to theorientation shown in FIG. 8M or a similar orientation, the inputindicator 812 is displayed. The input indicator 812 is semi-transparentand is displayed overlapping the other elements on the display screen504. In some embodiments, the input indicator 812 is displayed when themovement of the electronic device 500 meets a minimum velocity oracceleration threshold. If the minimum velocity or accelerationthreshold is not met, then the input indicator 812 is not displayed. Insome embodiments, the input indicator 812 is an animated graphic thatmoves in the direction of movement of the electronic device 504 (e.g.,the input indicator 812 moves toward the top of the display screen 504in response to the user rotating their wrist away from their body). Inresponse to this movement of the electronic device 500, the predefinedresponses 814 a-814 e are scrolled up such that a predefined response inthe lower region of the display screen 504 (e.g., predefined response814 d) is moved toward the center region of the display screen 504. As aresult of the upward scroll, the predefined response at the top of thedisplay screen 504 (e.g., predefined response 814 a shown in FIG. 8L) isno longer displayed and a new predefined response 814 f is displayed atthe bottom of the display screen 504.

As shown in FIG. 8N, following the rotation of the display screen 504away from the user's body as shown in FIG. 8M, the predefined response814 d and input indicator 812 are displayed in the center region of thedisplay screen 504 to indicate that the list of predefined responses 814a-814 e is no longer being scrolled and the predefined responses 814b-814 f will remain in their displayed positions unless additional inputis provided by the user.

As shown in FIG. 8O, after the list of predefined responses is scrolledand the predefined response 814 d is displayed in the center region ofthe screen, the predefined response 814 c is highlighted. If noadditional input from the user is received within a predetermined time,then predefined response 814 d will be selected after the predeterminedtime.

As shown in FIGS. 8P-8U, after highlighting the predefined response 814d, the other predefined responses are removed from the display screen504 if no additional input is received from the user within apredetermined time. In addition, a progress ring 816 and a selectionnotification 818 are displayed to indicate when the highlightedpredefined response 814 d will be sent as a response to the instantmessage 802 shown in FIG. 8A. The progress ring 816 is a graphicalelement that forms a circle over a second predetermined period of time.The amount of time that has elapsed in the second predetermined periodof time is indicated by the portion of the progress ring 816 that hasbeen displayed. The selection notification 818 notifies the user thatthe highlighted predefined response 814 d will be sent once the secondpredetermined period of time corresponding to the progress ring 816 haselapsed. The sending of the predefined response 814 d can be canceled byperforming a variety of inputs with the electronic device 500. Forinstance, the user can rapidly and repeatedly rotate their wrist towardand away from their body to cancel the sending of the predefinedresponse 814 d. Alternatively or in addition, the user can touch thedisplay screen 504 or operate a physical input mechanism on theelectronic device to cancel the sending of the predefined response 814d. If no cancelation input is received before the predetermined periodof time has elapsed, then the electronic device 500 proceeds withsending the predefined response 814 d, as shown in FIG. 8V.

FIGS. 8W-8Z illustrate the dismiss affordance 806 being selected afterthe instant message 802 shown in FIG. 8A is received. As shown in FIG.8W, the instructional graphic 808 is displayed in the center region 810of the display screen 504, the reply affordance 804 is displayed in anupper region of the display screen 504, and the dismiss affordance 806is displayed in a lower region of the display screen 504 (same as shownin FIG. 8B).

As shown in FIG. 8X, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist toward their body(e.g., the electronic device 500 is tilted down such that the top of thedisplay screen 504 is moved upward relative to the bottom of the displayscreen 504). This movement corresponds to one of the movements indicatedby the instructional graphic 808. In response to the movement of theelectronic device 500 to this orientation or a similar orientation, aninput indicator 812 is displayed. The input indicator 812 issemi-transparent and is displayed overlapping the other elements on thedisplay screen 504. In some embodiments, the input indicator 812 isdisplayed when the movement of the electronic device 500 meets a minimumvelocity or acceleration threshold. If the minimum velocity oracceleration threshold is not met, then the input indicator 812 is notdisplayed. In some embodiments, the input indicator 812 is an animatedgraphic that moves in the direction of movement of the electronic device504 (e.g., the input indicator 812 moves toward the bottom of thedisplay screen 504 in response to the user rotating their wrist towardtheir body).

FIG. 8Y illustrates the orientation of the electronic device 500 beingfurther changed as a result of the user further rotating their wristaway from their body (e.g., the electronic device 500 is tilted downfurther such that the top of the display screen 504 is further movedupward relative to the bottom of the display screen 504). The inputindicator 812 is displayed overlapping the dismiss affordance 806 in thelower region of the display screen 504 to indicate to the user that themovement of the electronic device 500 corresponds to a selection of thedismiss operation associated with the dismiss affordance 806. In someembodiments, following the movement of the electronic device 500 intothe orientation shown in FIG. 8Y or a similar orientation, theelectronic device 500 is rotated back toward its original orientation(e.g., the orientation shown in FIG. 8W) within a predetermined timeperiod (e.g., the user makes a “flicking” motion with the electronicdevice 500, where the display screen 504 is quickly rotated toward theuser and then is immediately rotated back away from the user).

As shown in FIG. 8Z, following the rotation of the display screen 504toward the user's body as shown in FIGS. 8X-8Y, the dismiss affordance806 and overlapping input indicator 812 move toward the center region ofthe display screen 504. The movement of the dismiss affordance 806 andoverlapping input indicator 812 indicates that the previous movement ofthe electronic device 500 has resulted in a selection of the dismissoperation associated with the dismiss affordance 806. The electronicdevice 500 then carries out the dismiss operation, which replaces theuser interfaces of FIGS. 8A-8Z with a default user interface 820 (e.g. atime display) as shown in FIG. 8AA.

FIGS. 8AB-8AR illustrate exemplary user interfaces for responding to anincoming telephone call with an electronic device 500. The electronicdevice 500 includes a display screen 504 and a tilt sensor, among otherelements which can be found above and/or as discussed in reference toFIG. 5A. The display screen 504 can be a touch-sensitive display screen,and the tilt sensor can be an accelerometer 534, directional sensor 540(e.g., compass), gyroscope 536, motion sensor 538, and/or a combinationthereof. In the present example, device 500 is a wearable device on auser's wrist, such as a smart watch. As shown in FIG. 8AB, electronicdevice 500 is worn on the user's left wrist and is being held in aposition such that display screen 504 is directly visible to the user'seyes (while being substantially perpendicular to the ground), such as istypical for users when they are checking the time.

As shown in FIG. 8AB, an incoming call notification 822 is displayed ina center region 810 of the display screen 504 when the incomingtelephone call is received.

FIG. 9A illustrates an exemplary blood flow pattern associated with apositioning of a user's hand. FIGS. 9B-9H illustrate exemplary userinterfaces for interacting with an electronic device based on a bloodflow pattern, in accordance with some embodiments. The user interfacesin these figures are used to illustrate the processes described below,including the processes in FIG. 15 .

As shown in FIG. 9A, blood flow 950 changes in intensity over time basedon a positioning of a user's hand, as measured with a blood flow sensorlocated on the user's wrist. When the user's hand is a relaxed, openposition, the blood flow is at a low intensity, as shown at 952. Whenthe user clenches their hand (e.g., makes a fist with their hand), theblood flow increases in intensity, as shown at 954. As the strength ofthe clench increases (e.g., the user makes a tighter fist with theirhand), the blood flow intensity also increases, as shown at 956. Thesedifferent patterns of blood flow intensity can be measured with anelectronic device and used to perform operations with the electronicdevice.

FIGS. 9B-9H illustrate exemplary user interfaces for performingoperations with an electronic device 500 based on a positioning of auser's hand. The electronic device 500 includes a display screen 504 anda biological sensor, among other elements which can be found aboveand/or as discussed in reference to FIG. 5A. The display screen 504 canbe a touch-sensitive display screen, and the biological sensor can be anoptical sensor positioned in the electronic device to measure blood flowindicative of a clenched hand of the user. In the present example,device 500 is a wearable device on a user's wrist, such as a smartwatch.

As shown in FIG. 9B, an incoming call notification 902 is displayed whenan incoming telephone call is received. In addition, an answer callaffordance 904 and a decline call affordance 906 are displayed. In someembodiments, the incoming call notification 902, answer call affordance904, and decline call affordance 906 are displayed a predetermined timeafter the incoming telephone call is initially received and/or inresponse to a user action. For instance, in some embodiments, theincoming call notification 902, answer call affordance 904, and declinecall affordance 906 are displayed in response to the user lifting theirarm into a raised position where the display screen 504 is visible tothe user. Throughout the sequence of interactions shown in FIGS. 9B-9F,the answer call affordance 904 or the decline call affordance 906 can betouched by the user to perform their respective operations with theelectronic device 500 (e.g., answering the incoming call or decliningthe incoming telephone call, respectively). As shown in FIG. 9B, whenthe incoming call is initially received, the user's hand is in arelaxed, open position.

As shown in FIG. 9C, the user has changed the positioning of their handfrom the relaxed, open position to a clenched position (e.g., the usermakes a fist with their hand). In response to the clenched positioningof the user's hand, the answer call affordance 904 is enlarged in size.The change in visual appearance of the answer call affordance indicatesto the user that their clenched hand has been detected by the electronicdevice 500, and the answer call operation will be carried out if theuser's hand is held in the clenched position for a predetermined time.In some embodiments, the clenched position of the user's hand isdetermined by the electronic device 500 by detecting a predefinedpattern (e.g., an increase in blood flow intensity as shown in FIG. 9A)for a predetermined time with the biological sensor.

As shown in FIGS. 9D-9F, the user continues to hold their hand in aclenched position as shown in FIG. 9C. As a result of the usercontinuing to hold their hand in the clenched position, a progress ring908 is displayed with the answer call affordance 904. The progress ring908 indicates the predetermined amount of time the user should continueclenching their hand in order for the answer call operation to becarried out. As shown in FIGS. 9D-9F, the progress ring 908 is agraphical element that forms a circle as the predetermined amount oftime elapses. The amount of time that has elapsed is indicated by theamount of the progress ring 908 being displayed. If the user stopsholding their hand in a clenched position, then the progress ring 908will stop being displayed and the electronic device 500 will forgoperforming the answer call operation unless another input is receivedfrom the user before the incoming call stops being received. If the usercontinues holding their hand in the clenched position until thepredetermined amount of time has elapsed, then the electronic device 500proceeds with the answer call operation, as shown in FIG. 9H.

As shown in FIG. 9G, if the user continues holding their hand in theclenched position until the predetermined amount of time has elapsed,then the progress ring 828 is completed and the answer call affordance904 and progress ring 828 are enlarged in size. The change in visualappearance of the answer call affordance 904 and progress ring 828indicates that the user successfully held their hand in the clenchedposition for the predetermined amount of time, and that the answer calloperation is being initiated.

In response to the user holding their hand in the clenched position forthe predetermined amount of time, a call answering notification 910 isdisplayed, as shown in FIG. 9H. The call answering notification 910indicates to the user that an answer call operation has been initiatedby the electronic device 500. The answer call operation instructs theelectronic device 500 or other associated device to answer the incomingtelephone call.

FIGS. 10A-10P illustrate exemplary user interfaces for interacting withan electronic device without touching a display screen or other physicalinput mechanism, in accordance with some embodiments. The userinterfaces in these figures are used to illustrate the processesdescribed below, including the processes in FIGS. 16A-16B.

In particular, FIGS. 10A-10P illustrate exemplary user interfaces forperforming operations with an electronic device 500 based on apositioning of a user's hand and an orientation of the electronicdevice. The electronic device 500 includes a display screen 504, a tiltsensor, and a biological sensor, among other elements which can be foundabove and/or as discussed in reference to FIG. 5A. The display screen504 can be a touch-sensitive display screen. The biological sensor canbe an optical sensor positioned in the electronic device to measureblood flow indicative of a clenched hand of the user. The tilt sensorcan be an accelerometer 534, directional sensor 540 (e.g., compass),gyroscope 536, motion sensor 538, and/or a combination thereof. In thepresent example, device 500 is a wearable device on a user's wrist, suchas a smart watch.

As shown in FIG. 10A, an incoming call notification 1002 is displayed ina center region 1008 of the display screen 504 when an incomingtelephone call is received. In addition, an answer call affordance 1004and a decline call affordance 1006 are displayed. In some embodiments,the incoming call notification 1002, answer call affordance 1004, anddecline call affordance 1006 are displayed a predetermined time afterthe incoming telephone call is initially received and/or in response toa user action. For instance, in some embodiments, the incoming callnotification 1002, answer call affordance 1004, and decline callaffordance 1006 are displayed in response to the user lifting their arminto a raised position where the display screen 504 is visible to theuser. Throughout the sequence of interactions shown in FIGS. 10A-10D and10G-10H, the answer call affordance 1004 or the decline call affordance1006 can be touched by the user to perform their respective operationswith the electronic device 500 (e.g., answering the incoming call ordeclining the incoming telephone call, respectively). As shown in FIG.10A, when the incoming call is initially received, the user's hand is ina relaxed, open position.

As shown in FIG. 10B, the user has changed the positioning of their handfrom the relaxed, open position to a clenched position (e.g., the usermakes a fist with their hand). In response to the clenched position ofthe user's hand, a clenching indicator 1010 is displayed. In someembodiments, the clenched position of the user's hand is determined bythe electronic device 500 by detecting a predefined pattern (e.g., anincrease in blood flow intensity as shown in FIG. 9A) for apredetermined time with the biological sensor. The clenching indicator1010 is semi-transparent and is displayed overlapping the other elementson the display screen 504. In some embodiments, the clenching indicator1010 is an animated graphic that enlarges in size based on the strengthof the clench of the user's hand (e.g., the user makes a tighter fistwith their hand and the blood flow intensity increases as shown in FIG.9A). The clenching indicator 1010 indicates to the user that theirclenched hand has been detected by the electronic device 500, and thatadditional input can be provided to the electronic device 500. As shownin FIG. 10B, the electronic device 500 is worn on the user's left wristand is being held in a position such that display screen 504 is directlyvisible to the user's eyes (while being substantially perpendicular tothe ground), such as is typical for users when they are checking thetime.

While the user's hand is clenched as shown in FIG. 10B, the user canchange the orientation of the electronic device 500 to perform theoperations associated with the answer call affordance 1004 or thedecline call affordance 1006. The changes in orientation includerotating the display screen 504 away from the user's body (e.g., theuser rotates their wrist to move the bottom of the display screen 504upward relative to the top of the display screen 504) or rotating thedisplay screen 504 toward the user's body (e.g., the user rotates theirwrist to move the top of the display screen 504 upward relative to thebottom of the display screen 504). In some embodiments, the operationsare performed when the movement of the electronic device 500 meets aminimum velocity or acceleration threshold. If the minimum velocity oracceleration threshold is not met, then the operations are notperformed.

As shown in FIG. 10C, after the user clenches their hand, theorientation of the electronic device 500 is changed into a downwardorientation as a result of the user rotating their wrist toward theirbody (e.g., the electronic device 500 is tilted down such that the topof the display screen 504 is moved upward relative to the bottom of thedisplay screen 504). In response to the movement of the electronicdevice 500 to this orientation or a similar orientation, the answer callaffordance 1004 is enlarged in size and moves toward the center regionof the display screen 504, as shown in FIG. 10D. The change in visualappearance and location of the answer call affordance 1004 indicates tothe user that the answer call operation will be selected as a result ofthis change in orientation of the electronic device 500 while the user'shand is in the clenched position. In addition, the visual appearance ofthe decline call affordance 1006 can be changed (e.g., darkened inbrightness or partially faded) to indicate that the decline calloperation will not be selected as a result of this change in orientationof the electronic device 500 while the user's hand is in the clenchedposition.

As shown in FIG. 10D, the electronic device 500 is held in the same orsimilar downward orientation as shown in FIG. 10C. Alternatively, insome embodiments, the orientation of the electronic device 500 isfurther changed into a further downward orientation as a result of theuser further rotating their wrist toward their body (e.g., theelectronic device 500 is tilted down further such that the top of thedisplay screen 504 is further moved upward relative to the bottom of thedisplay screen 504). As a result of the electronic device 500 being heldin this downward orientation, the answer call affordance 1004 isdisplayed in the center region of the display screen 504. In addition,an answer call notification 1012 is displayed on the display screen 504.The answer call notification 1012 notifies the user that the answer calloperation will be carried out in response the user clenching their handand moving the electronic device 500 into the downward orientation. Theanswer call operation can be canceled if the user changes theorientation of the electronic device 500 to a substantially differentorientation or if the user stops holding their hand in the clenchedposition. If the user continues holding their hand in the clenchedposition and holding the electronic device 500 in the downwardorientation, then the electronic device 500 proceeds with the answercall operation, as shown in FIG. 10F.

As shown in FIG. 10E, the user releases their hand from the clenchedposition (e.g., the user moves their hand to a relaxed, open position)while continuing to hold the electronic device 500 in the downwardorientation. In response to the user releasing their hand from theclenched position, the answer call affordance 1004 is further enlargedin size. The change in appearance of the answer call affordance 1004indicates that as a result of the user releasing their hand from theclenched position while holding the electronic device 500 in thedownward orientation, the answer call operation is being initiated.Alternatively, in some embodiments, the answer call operation isinitiated if the user holds their hand in the clenched position andholds the electronic device 500 in the downward orientation for apredetermined amount of time.

In response to the user releasing their hand from the clenched positionwhile holding the electronic device 500 in the downward orientation, acall answering notification 1014 is displayed, as shown in FIG. 10F.Alternatively, in some embodiments, the call answering notification 1014is displayed in response to the user holding their hand in the clenchedposition and holding the electronic device 500 in the downwardorientation for a predetermined amount of time. The call answeringnotification 1014 indicates to the user that an answer call operationhas been initiated by the electronic device 500. The answer calloperation instructs the electronic device 500 or other associated deviceto answer the incoming telephone call.

As shown in FIG. 10G, after the user clenches their hand, theorientation of the electronic device 500 is changed into a upwardorientation as a result of the user rotating their wrist away from theirbody (e.g., the electronic device 500 is tilted up such that the bottomof the display screen 504 is moved upward relative to the top of thedisplay screen 504). In response to the movement of the electronicdevice 500 to this orientation or a similar orientation, the declinecall affordance 1006 is enlarged in size and moves toward the centerregion of the display screen 504, as shown in FIG. 10H. The change invisual appearance and location of the decline call affordance 1006indicates to the user that the decline call operation will be selectedas a result of this change in orientation of the electronic device 500while the user's hand is in the clenched position. In addition, thevisual appearance of the answer call affordance 1004 can be changed(e.g., darkened in brightness or partially faded) to indicate that theanswer call operation will not be selected as a result of this change inorientation of the electronic device 500 while the user's hand is in theclenched position.

As shown in FIG. 10H, the electronic device 500 is held in the same orsimilar upward orientation as shown in FIG. 10G. Alternatively, in someembodiments, the orientation of the electronic device 500 is furtherchanged into a further upward orientation as a result of the userfurther rotating their wrist away from their body (e.g., the electronicdevice 500 is tilted up further such that the bottom of the displayscreen 504 is further moved upward relative to the top of the displayscreen 504). As a result of the electronic device 500 being held in thisupward orientation, the decline call affordance 1006 is displayed in thecenter region of the display screen 504. In addition, a decline callnotification 1016 is displayed on the display screen 504. The declinecall notification 1016 notifies the user that the decline call operationwill be carried out in response the user clenching their hand and movingthe electronic device 500 into the upward orientation. The decline calloperation can be canceled if the user changes the orientation of theelectronic device 500 to a substantially different orientation or if theuser stops holding their hand in the clenched position. If the usercontinues holding their hand in the clenched position and holding theelectronic device 500 in the upward orientation, then the electronicdevice 500 proceeds with the decline call operation, as shown in FIG.10J.

As shown in FIG. 10I, the user releases their hand from the clenchedposition (e.g., the user moves their hand to a relaxed, open position)while continuing to hold the electronic device 500 in the upwardorientation. In response to the user releasing their hand from theclenched position, the decline call affordance 1006 is further enlargedin size. The change in appearance of the decline call affordance 1006indicates that as a result of the user releasing their hand from theclenched position while holding the electronic device 500 in the upwardorientation, the decline call operation is being initiated.Alternatively, in some embodiments, the decline call operation isinitiated if the user holds their hand in the clenched position andholds the electronic device 500 in the upward orientation for apredetermined amount of time.

In response to the user releasing their hand from the clenched positionwhile holding the electronic device 500 in the upward orientation, acall ending notification 1018 is displayed, as shown in FIG. 10J.Alternatively, in some embodiments, the call ending notification 1018 isdisplayed in response to the user holding their hand in the clenchedposition and holding the electronic device 500 in the upward orientationfor a predetermined amount of time. The call ending notification 1018indicates to the user that a decline call operation has been initiatedby the electronic device 500. The decline call operation instructs theelectronic device 500 or other associated device to decline the incomingtelephone call.

As shown in FIG. 10K, a portion of an electronic document 1020 isdisplayed on the display screen 504. The electronic document 1020 can bea portion of any type of graphical content, such as a website, email,book, photograph, or message. As shown in FIG. 10K, when the portion ofthe electronic document 1020 initially displayed, the user's hand is ina relaxed, open position.

As shown in FIG. 10L, the orientation of the electronic device 500 ischanged as a result of the user rotating their wrist away from theirbody (e.g., the electronic device 500 is tilted up such that the bottomof the display screen 504 is moved upward relative to the top of thedisplay screen 504). Because the user's hand remains in the relaxed,open position, the portion of the electronic document 1020 beingdisplayed does not change in response to this change in orientation ofthe electronic device 500.

As shown in FIG. 10M, the user has changed the positioning of their handfrom the relaxed, open position to a clenched position (e.g., the usermakes a fist with their hand). In response to the clenched position ofthe user's hand, a clenching indicator 1010 is displayed. In someembodiments, the clenched position of the user's hand is determined bythe electronic device 500 by detecting a predefined pattern (e.g., anincrease in blood flow intensity as shown in FIG. 9A) for apredetermined time with the biological sensor. The clenching indicator1010 is semi-transparent and is displayed overlapping the other elementson the display screen 504. In some embodiments, the clenching indicator1010 is an animated graphic that enlarges in size based on the strengthof the clench of the user's hand (e.g., the user makes a tighter fistwith their hand and the blood flow intensity increases as shown in FIG.9A). The clenching indicator 1010 indicates to the user that theirclenched hand has been detected by the electronic device 500, and thatadditional input can be provided to the electronic device 500.

While the user's hand is clenched, the user can change the orientationof the electronic device 500 to scroll the portion of the electronicdocument 1020 being displayed. The changes in orientation includerotating the display screen 504 away from the user's body to scrollupward (e.g., the user rotates their wrist to move the bottom of thedisplay screen 504 upward relative to the top of the display screen 504)or rotating the display screen 504 toward the user's body to scrolldownward (e.g., the user rotates their wrist to move the top of thedisplay screen 504 upward relative to the bottom of the display screen504).

As shown in FIG. 10N, after the user clenches their hand, theorientation of the electronic device 500 is changed into a downwardorientation as a result of the user rotating their wrist toward theirbody (e.g., the electronic device 500 is tilted down such that the topof the display screen 504 is moved upward relative to the bottom of thedisplay screen 504). In response to the movement of the electronicdevice 500 to this orientation or a similar orientation, the electronicdocument 1020 is scrolled downward so that a different portion of theelectronic document 1020 is displayed on the display screen 504, asshown in FIG. 10N. The clenching indicator 1010 continues to bedisplayed while the user's hand is clenched.

Similarly, the electronic document 1020 can be scrolled upward by theuser clenching their hand and rotating their wrist away from their bodyto change the orientation of the electronic device 500 into an upwardorientation (e.g., the electronic device 500 is tilted up such that thebottom of the display screen 504 is moved upward relative to the top ofthe display screen 504).

As shown in FIG. 10O, the orientation of the electronic device 500 isfurther changed into a further downward orientation as a result of theuser further rotating their wrist toward their body (e.g., theelectronic device 500 is tilted down further such that the top of thedisplay screen 504 is further moved upward relative to the bottom of thedisplay screen 504). As a result of the electronic device 500 being heldin this downward orientation, the electronic document 1020 is scrolledfurther downward so that a different portion of the electronic document1020 is displayed on the display screen 504, as shown in FIG. 10O. Theclenching indicator 1010 continues to be displayed while the user's handis clenched. In some embodiments, if the user continues holding theirhand in the clenched position and holding the electronic device 500 inthe downward orientation, then the electronic device 500 continues toscroll the electronic document downward.

Similarly, in some embodiments, if the user continues holding their handin the clenched position and holding the electronic device 500 in theupward orientation (e.g., by rotating their wrist away from their body),then the electronic device 500 continues to scroll the electronicdocument upward.

As shown in FIG. 10P, the user releases their hand from the clenchedposition and holds their hand in a relaxed, open position. In responseto the user moving their hand to the relaxed, open position, theclenching indicator 1010 is removed from the display. In addition, theelectronic document 1020 stops being scrolled regardless of theorientation of the electronic device 500.

FIGS. 11A-11D illustrate exemplary user interfaces for interacting withan electronic device without touching a display screen or other physicalinput mechanism, in accordance with some embodiments. The userinterfaces in these figures are used to illustrate the processesdescribed below, including the processes in FIGS. 17A-17B.

In particular, FIGS. 11A-11D illustrate exemplary user interfaces forperforming operations with an electronic device 500 based on anorientation of the electronic device. The electronic device 500 includesa display screen 504, a tilt sensor, and a biological sensor, amongother elements which can be found above and/or as discussed in referenceto FIG. 5A. The display screen 504 can be a touch-sensitive displayscreen. The biological sensor can be an optical sensor positioned in theelectronic device to measure blood flow indicative of a clenched hand ofthe user. The tilt sensor can be an accelerometer 534, directionalsensor 540 (e.g., compass), gyroscope 536, motion sensor 538, and/or acombination thereof. In the present example, device 500 is a wearabledevice on a user's wrist, such as a smart watch.

As shown in FIG. 11A, the electronic device 500 is initially in anorientation where the display screen 504 is not visible to the userand/or the display screen 504 is in a passive mode. For instance, theuser's arm can be to side of the user's body. Alternatively, in someembodiments, the display screen 504 of the electronic device 500 isvisible to user but in the passive mode (e.g., the display screen 504 isoff or displaying passive information, such as a time).

As shown in FIG. 11B, an incoming call notification 1102, answer callaffordance 1104, and decline call affordance 1106 are displayed on thedisplay screen 504 (similar to FIGS. 6A, 7A, 8AS, and 9B). When anincoming telephone call is being received, the incoming callnotification 1102, answer call affordance 1104, and decline callaffordance 1106 are displayed in response to the user changing theorientation of the electronic device 500 such that the display screen504 is visible to the user. In some embodiments, the change inorientation is the result of the user lifting their arm and/or rotatingtheir wrist. For example, as shown in FIG. 11B, the electronic device500 is worn on the user's left wrist and is being held in a positionsuch that display screen 504 is directly visible to the user's eyes(while being substantially perpendicular to the ground), such as istypical for users when they are checking the time. Throughout thesequence of interactions described in reference to FIGS. 11B-11C, theanswer call affordance 1004 or the decline call affordance 1006 can betouched by the user to perform their respective operations with theelectronic device 500 (e.g., answering the incoming call or decliningthe incoming telephone call, respectively).

When the incoming call notification 1102, answer call affordance 1104,and decline call affordance 1106 are displayed in response to the userchanging the orientation of the electronic device 500, the electronicdevice 500 enters an active mode where the user can provide additionalinput to perform an operation (e.g., answering the incoming call ordeclining the incoming telephone call). In some embodiments, theadditional input includes changing the positioning of the user's hand toa clenched position, as described in reference to FIGS. 9A-9H.Alternatively or in addition, in some embodiments, the additional inputincludes further changing the orientation of the electronic device 500(e.g., tilting the electronic device 500 to the left or right), asdescribed in reference to FIGS. 8AS-8BI). Alternatively or in addition,in some embodiments, prior to receiving the additional input from theuser, the electronic device 500 displays additional movement indicators(e.g., the incoming call track 608 of FIG. 6B or the movement indicators708 a-708 d of FIGS. 7B-7E). After the additional movement indicatorsare displayed, additional input is received from the user, whichincludes further changing the orientation of the electronic device 500(e.g., tilting the electronic device 500), as described in reference toFIG. 6C-6I or 7G-7Q.

In some embodiments, if the electronic device 500 does not first enterthe active mode before receiving additional input from the user, thenthe electronic device 500 forgoes performing the operations when theadditional input is received. For instance, if the user does not firstchange the orientation of the electronic device 500 such that thedisplay screen 504 is visible to the user, then the user clenching theirhand will not perform an answer call operation.

As shown in FIG. 11C, the answer call affordance 1104 is displayed in alower region of the display screen 504 and the decline call affordance1106 is displayed in an upper region of the display screen 504 (similarto FIG. 8AB). The incoming call notification 1102 is displayed in acenter region 1108 of the display screen 504. Similar to as described inreference to FIG. 11B, when an incoming telephone call is beingreceived, the incoming call notification 1102, answer call affordance1104, and decline call affordance 1106 are displayed in response to theuser changing the orientation of the electronic device 500 such that thedisplay screen 504 is visible to the user, which also results in theelectronic device 500 entering an active mode where the user can provideadditional input to perform an operation (e.g., answering the incomingcall or declining the incoming telephone call). In some embodiments, theadditional input includes further changing the orientation of theelectronic device 500 (e.g., rotating the display screen 504 away fromor toward the user), as described in reference to FIGS. 8AB-8AR).

In some embodiments, if the electronic device 500 does not first enterthe active mode before receiving additional input from the user, thenthe electronic device 500 forgoes performing the operations when theadditional input is received. For instance, if the user does not firstchange the orientation of the electronic device 500 such that thedisplay screen 504 is visible to the user, then the user rotating thedisplay screen 504 will not perform an answer call or decline calloperation.

As shown in FIG. 11D, a reply affordance 1114 is displayed in an upperregion of the display screen 504 and a dismiss affordance 1116 isdisplayed in a lower region of the display screen (similar to FIG. 8B).In addition, an instructional graphic 1110 can be displayed in thecenter region 1108 of the display screen. Similar to as described inreference to FIG. 11B, after an instant message is received, the replyaffordance 1114 and dismiss affordance 1116 are displayed in response tothe user changing the orientation of the electronic device 500 such thatthe display screen 504 is visible to the user, which also results in theelectronic device 500 entering an active mode where the user can provideadditional input to perform an operation (e.g., answering the incomingcall or declining the incoming telephone call). In some embodiments, theadditional input includes further changing the orientation of theelectronic device 500 (e.g., rotating the display screen 504 away fromor toward the user), as described in reference to FIGS. 8B-8E and8W-8Z).

In some embodiments, if the electronic device 500 does not first enterthe active mode before receiving additional input from the user, thenthe electronic device 500 forgoes performing the operations when theadditional input is received. For instance, if the user does not firstchange the orientation of the electronic device 500 such that thedisplay screen 504 is visible to the user, then the user rotating thedisplay screen 504 will not perform a reply or dismiss operation.

In some embodiments, if the electronic device 500 enters the active modeand no additional input is received from the user, then the displayscreen 504 is activated and displays a time or a default “home”interface.

FIGS. 12A-12B are flow diagrams illustrating a method 1200 forperforming one or more operations with an electronic device, inaccordance with some embodiments. Method 1200 can be performed at adevice (e.g., 100, 300, 500) with a display screen and a tilt sensor. Insome examples, the tilt sensor includes an accelerometer, directionalsensor (e.g., compass), gyroscope, motion sensor, and/or a combinationthereof. Some operations in method 1200 are, optionally, combined, theorder of some operations are, optionally, changed, and some operationsare, optionally, omitted.

As described below, method 1200 provides an intuitive way forinteracting with the device. In some cases, the device performs anoperation in response to the user's hand, arm, and/or wrist movement.Performing an operation in response to the user's hand, arm, and/orwrist movement enhances the operability of the device by enabling theuser to interact with the device without touching the display screen orother physical input mechanisms. This also allows operations to beperformed more quickly and efficiently with the device.

As shown in method 1200, in some embodiments, the device (1202) displaysa first graphical element at a first location on the display screen(e.g., graphical object 614 of FIG. 6B). The device also (1204) displaysa second graphical element at a second location on the display screen(e.g., answer call affordance 604 of FIG. 6B). The second graphicalelement is associated with a first operation (e.g., answering anincoming telephone call). In some examples, the device displays agraphical indication of a path for simulated movement of the firstgraphical element (e.g., displays incoming call track 608 of FIG. 6B).

As shown in method 1200, in some embodiments, the device (1206) receivesa tilt sensor input associated with movement of the electronic device(e.g., the orientation of the electronic device 500 is changed as aresult of the user moving their arm/wrist/hand as shown in FIGS. 6C-6G).The device (1220) can optionally, while receiving the tilt sensor input,display the first graphical element at locations on the display screenbased on the tilt sensor input (e.g., graphical object 614 is displayedat intermediate locations along the incoming call track 608 as shown inFIGS. 6C-6F).

As shown in method 1200, in some embodiments, in accordance with adetermination that the tilt sensor input satisfies a first predefinedtilt sensor condition (e.g., the tilt sensor input results in thegraphical object 614 moving to the answer call affordance 604 as shownin FIG. 6G), the device (1208) displays the first graphical elementproximate to the second location on the display screen (e.g., graphicalobject 614 is displayed at the end of the right track segment 610 asshown in FIG. 6G). Furthermore, in accordance with the determinationthat the tilt sensor input satisfies the first predefined tilt sensorcondition, the device also (1210) performs the first operationassociated with the second graphical element (e.g., answers an incomingtelephone call as shown in FIGS. 6I-6K). Performing the first operationin response to the determination that the tilt sensor input satisfiesthe first predefined tilt sensor condition allows the first operation tobe performed with fewer physical inputs from the user (e.g. fingertouches on the display screen). Reducing the number of inputs needed toperform an operation enhances the operability of the device and makesthe user-device interface more efficient (e.g., by helping the user toprovide proper inputs and reducing user mistakes whenoperating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In some examples, the first predefined tilt sensor condition includessimulated physical movement of a virtual object (having virtual mass)corresponding to the first graphical element (e.g., the acceleration andvelocity of the graphical object 614 as it moves along the incoming calltrack 608 is representative of how a physical ball would roll along aphysical track being held in the same orientation as the electronicdevice 500 as shown in FIGS. 6C-6F). In some examples, the simulatedphysical movement of the virtual object is based at least in part on atilt angle of the device over a period of time. In some examples, thepredefined tilt sensor condition is satisfied when the simulatedphysical movement of the virtual object results in the virtual objectbeing moved proximate to the second location on the display screen(e.g., graphical object 614 is moved to the end of the right tracksegment 610 as shown in FIG. 6G). In some examples, the device includesa haptic feedback mechanism, and, further in accordance with thedetermination that the tilt sensor input satisfies the first predefinedtilt sensor condition, the device provides a haptic feedback via thehaptic feedback mechanism. In some examples, the first operationincludes answering an incoming telephone call or declining an incomingtelephone call.

In some examples, the device (1214) optionally displays a thirdgraphical element at a fourth location on the display screen (e.g.,decline call affordance 606 of FIG. 6B). The third graphical element isassociated with a second operation (e.g., declining an incomingtelephone call). In some examples, the second graphical element is anaffordance associated with the first operation (e.g., answer callaffordance 604 of FIG. 6B) and the third graphical element is anaffordance associated with the second operation (e.g., decline callaffordance 606 of FIG. 6B). In accordance with a determination that thetilt sensor input satisfies a second predefined tilt sensor condition(e.g., the tilt sensor input results in the ball rolling to the declinecall affordance), the device (1216) displays the first graphical elementproximate to the fourth location on the display screen (e.g., graphicalobject 614 is displayed at the end of the left track segment 612 of FIG.6G) and (1218) performs the second operation associated with the thirdgraphical element (e.g., declines the incoming telephone call).

As shown in method 1200, in some embodiments, in accordance with adetermination that the tilt sensor input fails to satisfy the first orsecond predefined tilt sensor conditions (e.g., the tilt sensor inputdoes not result in the graphical object 614 moving to the answer callaffordance 604 or the decline call affordance 606 as shown in FIG. 6G),the device (1212) displays the first graphical element at a thirdlocation on the display screen based on the tilt sensor input (e.g.,graphical object 614 is displayed at its initial location on theincoming call track 608 as shown in FIG. 6B or at intermediate locationsalong the incoming call track 608 as shown in FIGS. 6C-6F). In someexamples, the third location is the same as the first location (e.g.,graphical object 614 is displayed at its initial location on theincoming call track 608 as shown in FIG. 6B). In some examples, thepredefined tilt sensor condition is not satisfied when the simulatedphysical movement of the virtual object does not result in the virtualobject being moved proximate to the second location on the displayscreen (e.g., graphical object 614 is moved to its initial location onthe incoming call track 608 as shown in FIG. 6B or moved to intermediatelocations along the incoming call track 608 as shown in FIGS. 6C-6F).

Note that details of the processes described above with respect tomethod 1200 (e.g., FIGS. 12A-12B) are also applicable in an analogousmanner to other methods described herein. For example, method 1700optionally includes one or more of the characteristics of the variousmethods described above with reference to method 1200. For example, themode change criteria of method 1700 can be satisfied prior to receivingthe tilt sensor input of method 1200 (e.g., the display screen is heldin view of a user for a predetermined time as a precondition to ptoreceiving the tilt sensor input). For brevity, these details are notrepeated below.

FIGS. 13A-13B are flow diagrams illustrating a method 1300 forperforming one or more operations with an electronic device, inaccordance with some embodiments. Method 1300 is performed at a device(e.g., 100, 300, 500) with a display screen and a tilt sensor. In someexamples, the tilt sensor includes an accelerometer, directional sensor(e.g., compass), gyroscope, motion sensor, and/or a combination thereof.Some operations in method 1300 are, optionally, combined, the order ofsome operations are, optionally, changed, and some operations are,optionally, omitted.

As described below, method 1300 provides an intuitive way forinteracting with the device. In some cases, the device performs anoperation in response to the user's hand, arm, and/or wrist movement.Performing an operation in response to the user's hand, arm, and/orwrist movement enhances the operability of the device by enabling theuser to interact with the device without touching the display screen orother physical input mechanisms. This also allows operations to beperformed more quickly and efficiently with the device.

As shown in method 1300, in some embodiments, the device (1302) displaysa first plurality of graphical elements (e.g., movement indicators 708a-708 d of FIGS. 7B-7E) indicating a predefined sequence of movementsassociated with an operation (e.g., answering an incoming telephonecall). The first plurality of graphical elements include a firstgraphical element indicating a first movement (e.g., a “high” musicalnote as shown in FIG. 7B) and a second graphical element indicating asecond movement (e.g., a “low” musical note as shown in FIG. 7C). Thefirst movement includes rotation of the device in a first directionaround a central axis from a neutral position to a first position andback toward the neutral position within a first predetermined time(e.g., the user makes a “flicking” motion with the device, where thedisplay screen is quickly rotated away from the user and then isimmediately rotated back toward the user). The second movement comprisesa rotation of the electronic device in a second direction opposite thefirst direction around the central axis from the neutral position to asecond position and back toward the neutral position within a secondpredetermined time (e.g., the user makes a “flicking” motion with thedevice, where the display screen is quickly rotated toward the user andthen is immediately rotated back away from the user). In some examples,the central axis corresponds to an axis of rotation of a user's wrist.In some examples, the first or second movement includes rotation of thedevice at a velocity greater than a predetermined minimum velocity. Insome examples, the first or second movement includes rotation of theelectronic device with an acceleration greater than a predeterminedminimum acceleration.

As shown in method 1300, in some embodiments, the device (1304) receivesa plurality of tilt sensor inputs associated with movements of theelectronic device (e.g., the orientation of the device is changed asshown in FIGS. 7G-7N). In some examples, while receiving the pluralityof tilt sensor inputs, the device (1310) optionally displays a secondplurality of graphical elements indicating movements of the electronicdevice (e.g., movement indicators 708 a-708 d of FIGS. 7G-7N). In someexamples, while receiving the plurality of tilt sensor inputs, thedevice (1312) optionally displays an indicator that indicates thedirection of rotation of the electronic device (e.g., input indicator710 of FIGS. 7G-7N).

As shown in method 1300, in some embodiments, in accordance with adetermination that the plurality of tilt sensor inputs corresponds tothe predefined sequence of movements indicated by the first plurality ofgraphical elements (e.g., the tilt sensor input corresponds to themovement indicators 708 a-708 d shown in FIGS. 7B-7E), the device (1306)performs the operation associated with the predefined sequence ofmovements. In some examples, the operation includes answering anincoming telephone call or declining the incoming telephone call.Performing the operation in response to the determination that theplurality of tilt sensor inputs corresponds to the predefined sequenceof movements indicated by the first plurality of graphical elementsallows the first operation to be performed with fewer physical inputsfrom the user (e.g. finger touches on the display screen). Reducing thenumber of inputs needed to perform an operation enhances the operabilityof the device and makes the user-device interface more efficient (e.g.,by helping the user to provide proper inputs and reducing user mistakeswhen operating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

As shown in method 1300, in some embodiments, in accordance with adetermination that the plurality of tilt sensor inputs does notcorrespond to the predefined sequence of movements indicated by thefirst plurality of graphical elements (e.g., the tilt sensor input doesnot correspond to the movement indicators 708 a-708 d shown in FIGS.7B-7E), the device (1308) forgoes performing the operation associatedwith the predefined sequence of movements. In some examples, inaccordance with a determination that at least one of the plurality oftilt sensor inputs is not greater than a predetermined minimum velocity,the device (1314) optionally forgoes performing the operation associatedwith the predefined sequence of movements. In some examples, inaccordance with a determination that at least one of the plurality oftilt sensor inputs is not greater than a predetermined minimumacceleration, the device (1316) optionally forgoes performing theoperation associated with the predefined sequence of movements.

Note that details of the processes described above with respect tomethod 1300 (e.g., FIGS. 13A-13B) are also applicable in an analogousmanner to other methods described herein. For example, method 1700optionally includes one or more of the characteristics of the variousmethods described above with reference to method 1300. For example, themode change criteria of method 1700 can be satisfied prior to receivingthe tilt sensor inputs of method 1300 (e.g., the display screen is heldin view of a user for a predetermined time as a precondition toreceiving the tilt sensor inputs). For brevity, these details are notrepeated below.

FIG. 14 is a flow diagram illustrating a method 1400 for performing oneor more operations with an electronic device, in accordance with someembodiments. Method 1400 is performed at a device (e.g., 100, 300, 500)with a display screen and a tilt sensor. In some examples, the tiltsensor includes an accelerometer, directional sensor (e.g., compass),gyroscope, motion sensor, and/or a combination thereof. Some operationsin method 1400 are, optionally, combined, the order of some operationsare, optionally, changed, and some operations are, optionally, omitted.

As described below, method 1400 provides an intuitive way forinteracting with the device. In some cases, the device performs anoperation in response to the user's hand, arm, and/or wrist movement.Performing an operation in response to the user's hand, arm, and/orwrist movement enhances the operability of the device by enabling theuser to interact with the device without touching the display screen orother physical input mechanisms. This also allows operations to beperformed more quickly and efficiently with the device.

As shown in method 1400, in some embodiments, the device (1402) displaysa first item (e.g., reply affordance 804 of FIG. 8B, a predefinedresponse 814 a-814 e of FIG. 8E, or decline call affordance 826 of FIG.8AB or 8AS) at a first position on the display screen and a second item(e.g., dismiss affordance 806 of FIG. 8B, a predefined response 814a-814 e of FIG. 8E, or answer call affordance 824 of FIG. 8AB or 8AS) ata second position on the display screen. The first position and secondposition correspond to positions along a line substantiallyperpendicular to an axis of rotation of the electronic device (e.g.,items are positioned vertically or horizontally on the display screen sothat rotation of the device is toward one item or the other, such asshown in FIG. 8B, 8F, 8AB, or 8AS). In some examples, the axis ofrotation of the device corresponds to an axis of rotation of a user'swrist. In some examples, the first position is in an upper half of thedisplay screen and the second position is in a lower half of the displayscreen. In some examples, the first or second item is a reply commandfor a received text message, a dismiss command for a received textmessage, a predefined response to a received text message, an answercommand for a telephone call, or a decline command for a telephone call.

As shown in method 1400, in some embodiments, the device (1404) receivesa tilt sensor input associated with movement of the electronic device(e.g., the orientation of the device is changed as shown in FIG. 8C-8E,8G, 8J, 8M, 8X-8Y, 8AC-8AI, 8AK-8AQ, 8AT-8AZ, or 8BB-8BH). In someexamples, the device (1412) optionally displays an indicator thatindicates the direction of rotation of the electronic device (e.g.,input indicator 812 of FIG. 8C-8D, 8G, 8J, 8M, or 8X-8Y). In someexamples, the tilt sensor input corresponds to rotation of the device inthe first or second direction at a velocity greater than a predeterminedminimum velocity. In some examples, the tilt sensor input corresponds torotation of the device in the first or second direction with anacceleration greater than a predetermined minimum acceleration.

As shown in method 1400, in some embodiments, in accordance with adetermination that the tilt sensor input corresponds to a rotation ofthe electronic device in a first direction around the axis of rotationfrom a neutral position to a first position (e.g., the orientation ofthe device is changed as shown in FIG. 8C-8E, 8J, 8M, 8AK-8AQ, or8BB-8BH), the device (1406) moves the first item from the first positionon the display screen to a third position along the line substantiallyperpendicular to the axis of rotation (e.g., reply affordance 804, apredefined response 814 a-814 e, or decline call affordance 826 is movedtoward a center region of the display screen, as shown in FIG. 8C-8E,8J, 8M, 8AK-8AQ, or 8BB-8BH). In some examples, the tilt sensor inputcorresponds to a rotation of the electronic device in the firstdirection around the axis of rotation from the neutral position to thefirst position and from the first position back toward the neutralposition within a first predetermined time (e.g., the user makes a“flicking” motion with the device, where the display screen is quicklyrotated away from the user and then is immediately rotated back towardthe user).

As shown in method 1400, in some embodiments, in accordance with adetermination that the tilt sensor input corresponds to a rotation ofthe electronic device in a second direction opposite the first directionaround the axis of rotation from the neutral position to a secondposition (e.g., the orientation of the device is changed as shown inFIG. 8G, 8X-8Y, 8AC-8AI, or 8AT-8AZ), the device (1408) moves the seconditem from the second position on the display screen to a fourth positionalong the line substantially perpendicular to the axis of rotation(e.g., dismiss affordance 806, a predefined response 814 a-814 e, oranswer call affordance 824 is moved toward a center region of thedisplay, as shown in FIG. 8G, 8X-8Y, 8AC-8AI, or 8AT-8AZ). In someexamples, the tilt sensor input corresponds to a rotation of theelectronic device in the second direction opposite the first directionaround the axis of rotation from the neutral position to the secondposition and from the second position back toward the neutral positionwithin a second predetermined time (e.g., the user makes a “flicking”motion with the device, where the display screen is quickly rotatedtoward the user and then is immediately rotated back away from theuser).

Moving the first or second items to different positions on the displayscreen in response to the determination that the tilt sensor inputcorresponds to a rotation of the device allows the device to be operatedwith fewer physical inputs from the user (e.g. finger touches on thedisplay screen). Reducing the number of inputs needed to perform anoperation enhances the operability of the device and makes theuser-device interface more efficient (e.g., by helping the user toprovide proper inputs and reducing user mistakes whenoperating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

In some examples, the third and fourth positions are in a center regionof the display screen. In some examples, the device includes a hapticfeedback mechanism (e.g., vibration mechanism), and, in accordance withthe determination that the tilt sensor input corresponds to rotation ofthe device in the first or second direction, the device provides ahaptic feedback, via the haptic feedback mechanism. In some examples, inaccordance with a determination that the tilt sensor input is notgreater than a predetermined minimum velocity, the device forgoes movingthe first or second item. In some examples, in accordance with adetermination that the tilt sensor input is not greater than apredetermined minimum acceleration, the device forgoes moving the firstor second item.

In some examples, after moving the first or second item, and inaccordance with a determination that no additional tilt sensor inputabove a threshold value is received within a predetermined time, thedevice (1410) optionally selects the moved item (e.g., the replyaffordance 804 is selected as shown in FIG. 8E, the predefined response814 d is selected as shown in FIG. 8U, the dismiss affordance 806 isselected as shown in FIG. 8Z, the answer call affordance 824 is selectedas shown in FIG. 8AI or 8AZ, or the decline call affordance is selectedas shown in FIG. 8AQ or 8BH). In some examples, displaying a countdownindicator corresponding to the predetermined time (e.g., progress ring816 of FIGS. 8P-8U or progress ring 828 of FIG. 8AD-8AI, 8AL-8AQ,8AU-8AZ, or 8BC-8BH). In some examples, the device includes a hapticfeedback mechanism (e.g., vibration mechanism), and, in accordance withthe determination that no additional tilt sensor input above thethreshold value is received within the predetermined time, the deviceprovides a haptic feedback, via the haptic feedback mechanism.

Note that details of the processes described above with respect tomethod 1400 (e.g., FIG. 14 ) are also applicable in an analogous mannerto other methods described herein. For example, method 1700 optionallyincludes one or more of the characteristics of the various methodsdescribed above with reference to method 1400. For example, the modechange criteria of method 1700 can be satisfied prior to receiving thetilt sensor input of method 1400 (e.g., the display screen is held inview of a user for a predetermined time as a precondition to receivingthe tilt sensor input). For brevity, these details are not repeatedbelow.

FIG. 15 is a flow diagram illustrating a method 1500 for performing anoperation with an electronic device, in accordance with someembodiments. Method 1500 is performed at a device (e.g., 100, 300, 500)with a display screen and a biological sensor. In some examples, thebiological sensor is an optical sensor positioned in the device tomeasure blood flow indicative of a clenched hand of the user. Someoperations in method 1500 are, optionally, combined, the order of someoperations are, optionally, changed, and some operations are,optionally, omitted.

As described below, method 1500 provides an intuitive way forinteracting with the device. In some cases, the device performs anoperation in response to a positioning of a user's hand. Performing anoperation in response to the positioning of the user's hand enhances theoperability of the device by enabling the user to interact with thedevice without touching the display screen or other physical inputmechanisms. This also allows operations to be performed more quickly andefficiently with the device.

As shown in method 1500, in some embodiments, the device (1502) displaysan affordance on the display screen (e.g., answer call affordance 904 ofFIG. 9B).

As shown in method 1500, in some embodiments, the device (1504) receivesbiological sensor input associated with a positioning of a user's hand(e.g., the user changes the positioning of their hand to a clenchedposition as shown in FIG. 9C).

As shown in method 1500, in some embodiments, in accordance with adetermination that the biological sensor input corresponds to apredefined pattern for a predetermined time, the predefined patternbeing associated with the positioning of the user's hand (e.g., the usercontinues to hold their hand in the clenched position for apredetermined amount of time as shown in FIGS. 9D-9G), the device (1506)displays an indication that the biological sensor input corresponds tothe predefined pattern for the predetermined time (e.g., the answer callaffordance 904 is enlarged in size and a progress ring 908 is displayed,as shown in FIGS. 9D-9G). In some examples, the device (1512) optionallymodifies a visual appearance of the affordance (e.g., the answer callaffordance 904 is enlarged in size as shown in FIGS. 9D-9G). In someexamples, the device (1514) optionally displays a graphical elementindicating the predetermined time (e.g., progress ring 908 of FIGS.9D-9G). In some examples, the device includes a haptic feedbackmechanism (e.g., vibration mechanism), and, further in accordance withthe determination that the biological sensor input corresponds to thepredefined pattern, the device provides a haptic feedback, via thehaptic feedback mechanism (e.g., the device vibrates when the userclenches their hand).

The device then (1508) performs an operation associated with theaffordance. In some examples, the operation includes answering atelephone call. Performing the operation in response to thedetermination that the biological sensor input corresponds to thepredefined pattern for the predetermined time allows the operation to beperformed with fewer physical inputs from the user (e.g. finger toucheson the display screen). Reducing the number of inputs needed to performan operation enhances the operability of the device and makes theuser-device interface more efficient (e.g., by helping the user toprovide proper inputs and reducing user mistakes whenoperating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

As shown in method 1500, in some embodiments, in accordance with adetermination that the sensor input does not correspond to thepredefined pattern for the predetermined time (e.g., the user stopsholding their hand in a clenched position), the device (1510) forgoesperforming the operation associated with the affordance (e.g., theincoming telephone call is not answered).

Note that details of the processes described above with respect tomethod 1500 (e.g., FIG. 15 ) are also applicable in an analogous mannerto other methods described herein. For example, method 1700 optionallyincludes one or more of the characteristics of the various methodsdescribed above with reference to method 1500. For example, the modechange criteria of method 1700 can be satisfied prior to receiving thebiological sensor input of method 1500 (e.g., the display screen is heldin view of a user for a predetermined time as a precondition toreceiving the biological sensor input). For brevity, these details arenot repeated below.

FIGS. 16A-16B are flow diagrams illustrating a method 1600 forperforming an operation with an electronic device, in accordance withsome embodiments. Method 1600 is performed at a device (e.g., 100, 300,500) with a display screen, a biological sensor, and a tilt sensor. Insome examples, the biological sensor is an optical sensor positioned inthe device to measure blood flow indicative of a clenched hand of theuser. In some examples, the tilt sensor includes an accelerometer,directional sensor (e.g., compass), gyroscope, motion sensor, and/or acombination thereof. Some operations in method 1600 are, optionally,combined, the order of some operations are, optionally, changed, andsome operations are, optionally, omitted.

As described below, method 1600 provides an intuitive way forinteracting with the device. In some cases, the device performs anoperation in response to a positioning of a user's hand and anorientation of the device. Performing an operation in response to thepositioning of the user's hand and the orientation of the deviceenhances the operability of the device by enabling the user to interactwith the device without touching the display screen or other physicalinput mechanisms. This also allows operations to be performed morequickly and efficiently with the device.

As shown in method 1600, in some embodiments, the device (1602) displaysa user interface on the display screen (e.g., an incoming telephone callinterface as shown in FIG. 10A or an electronic document 1020 as shownin FIG. 10K). The user interface is responsive to at least a firstoperation and a second operation associated with movement of the device(e.g., an answer call operation, a decline call operation, a scroll upoperation, or a scroll down operation). In some examples, the userinterface includes a first graphical element associated with the firstoperation and a second graphical element associated with the secondoperation. In some examples, the first graphical element is a firstaffordance associated with an answer call operation (e.g., answer callaffordance 1004 of FIG. 10A), and the second graphical element is asecond affordance associated with a decline call operation (e.g.,decline call affordance 1006 of FIG. 10A). In some examples, the userinterface includes a portion of an electronic document (e.g., electronicdocument 1020 of FIG. 10K).

As shown in method 1600, in some embodiments, the device (1604) receivesbiological sensor input associated with positioning of a user's hand(e.g., the user changes the positioning of their hand to a clenchedposition as shown in FIGS. 10B and 10M).

As shown in method 1600, in some embodiments, in accordance with adetermination that the biological sensor input corresponds to apredefined pattern for a predetermined time, the predefined patternbeing associated with the positioning of the user's hand (e.g., the userholds their hand in the clenched position as shown in FIG. 11B-10D,10G-10H, or 10M-10O), the device (1606) displays an indication in theuser interface that the sensor input corresponds to the predefinedpattern (e.g., clenching indicator 1010 of FIG. 10B-10C, 10G, or10M-10O). In some examples, the device includes a haptic feedbackmechanism (e.g., vibration mechanism), and, further in accordance withthe determination that the biological sensor input corresponds to thepredefined pattern, providing a haptic feedback, via the haptic feedbackmechanism.

As shown in method 1600, in some embodiments, while the biologicalsensor input corresponds to the predefined pattern (e.g., while theuser's hand is in the clenched position as shown in FIG. 10B-10D,10G-10H, or 10M-10O), the device (1608) receives a tilt sensor inputassociated with movement of the electronic device (e.g., the orientationof the device is changed as shown in FIG. 10C-10E, 10G-10I, or 10N-10O).

As shown in method 1600, in some embodiments, in accordance with adetermination that the tilt sensor input corresponds to movement of afirst type (e.g., the orientation of the device is changed as shown inFIG. 10C-10E or 10N-10O), the device (1610) performs the first operation(e.g., answers the incoming telephone call as shown in FIG. 10F orscrolls the electronic document 1020 in a downward direction as shown inFIGS. 10N-10O). In some examples, in accordance with the determinationthat the tilt sensor input corresponds to movement of the first type,the device (1614) optionally modifies a visual appearance of the firstgraphical element (e.g., enlarges the size of the answer call affordance1004 as shown in FIGS. 10D-10E). In some examples, the first operationincludes scrolling the electronic document in a first direction (e.g.,electronic document 1020 of FIG. 10K is scrolled downward). In someexamples, the movement of the first type includes a rotation of thedevice in a first direction around a central axis from a neutralposition to a first position (e.g., the orientation of the device ischanged as shown in FIG. 10C-10E or 10N-10O). In some examples, themovement of the first type further comprises rotation from the firstposition back toward the neutral position within a first predeterminedtime (e.g., the user makes a “flicking” motion with the device, wherethe display screen is quickly rotated toward the user and then isimmediately rotated back away from the user). In some examples, afterreceiving the tilt sensor input and prior to performing the firstoperation, the device (1624) determines the biological sensor inputceases to correspond to the predefined pattern (e.g., the user releasestheir hand from the clenched position), and in response, the device(1610) performs the first operation (e.g., releasing the clenched handinitiates the answer call operation as shown in FIG. 10E).

As shown in method 1600, in some embodiments, in accordance with adetermination that the tilt sensor input corresponds to movement of asecond type (e.g., the orientation of the device is changed as shown inFIGS. 10G-10I), the device (1612) performs the second operation (e.g.,declines the incoming telephone call as shown in FIG. 10J or scrolls theelectronic document 1020 in an upward direction). In some examples, inaccordance with the determination that the tilt sensor input correspondsto movement of the second type, the device (1616) optionally modifies avisual appearance of the second graphical element (e.g., enlarges thesize of the decline call affordance 1006 as shown in FIGS. 10G-10I). Insome examples, the second operation including scrolling the electronicdocument in a second direction (e.g., electronic document 1020 of FIG.10K is scrolled upward). In some examples, the movement of the secondtype includes a rotation of the electronic device in a second directionaround a central axis from a neutral position to a second position(e.g., the orientation of the device is changed as shown in FIGS.10G-10I). In some examples, the movement of the second type furtherincludes rotation from the second position back toward the neutralposition within a second predetermined time (e.g., the user makes a“flicking” motion with the device, where the display screen is quicklyrotated away from the user and then is immediately rotated back towardthe user). In some examples, after receiving the tilt sensor input andprior to performing the second operation, the device (1626) determinesthe biological sensor input ceases to correspond to the predefinedpattern (e.g., the user releases their hand from the clenched position),and in response, the device (1612) performs the second operation (e.g.,releasing the clenched hand initiates the decline call operation asshown in FIG. 10I).

Performing the first or second operations based on tilt sensor input andbiological sensor input allows the device to be operated with fewerphysical inputs from the user (e.g. finger touches on the displayscreen). Reducing the number of inputs needed to perform an operationenhances the operability of the device and makes the user-deviceinterface more efficient (e.g., by helping the user to provide properinputs and reducing user mistakes when operating/interacting with thedevice) which, additionally, reduces power usage and improves batterylife of the device by enabling the user to use the device more quicklyand efficiently.

In some examples, the central axis corresponds to an axis of rotation ofa user's wrist. In some examples, the movement of the first or secondtype corresponds to movement of the electronic device at a velocitygreater than a predetermined minimum velocity. In some examples, inaccordance with a determination that the tilt sensor input is notgreater than a predetermined minimum velocity, the device forgoesperforming the first or second operations. In some examples, themovement of the first or second type corresponds to movement of theelectronic device with an acceleration greater than a predeterminedminimum acceleration. In some examples, in accordance with adetermination that the tilt sensor input is not greater than apredetermined minimum acceleration, the device forgoes performing thefirst or second operations.

In some examples, the device (1618) optionally determines that thebiological sensor input does not correspond to the predefined patternfor the predetermined time (e.g., the user releases their hand from theclenched position). In some examples, while the biological sensor inputdoes not correspond to the predefined pattern (e.g., while the user'shand is not clenched), the device (1620) receives the tilt sensor inputassociated with movement of the electronic device and (1622) optionallyforgoes performing the first or second operations.

Note that details of the processes described above with respect tomethod 1600 (e.g., FIGS. 16A-16B) are also applicable in an analogousmanner to other methods described herein. For example, method 1700optionally includes one or more of the characteristics of the variousmethods described above with reference to method 1600. For example, themode change criteria of method 1700 can be satisfied prior to receivingthe biological sensor input of method 1600 (e.g., the display screen isheld in view of a user for a predetermined time as a precondition toreceiving the biological sensor input). For brevity, these details arenot repeated below.

FIGS. 17A-17B are flow diagrams illustrating a method 1700 forperforming an operation with an electronic device, in accordance withsome embodiments. Method 1700 is performed at a device (e.g., 100, 300,500) with a display screen and a sensor. In some examples, the sensorincludes a tilt sensor. In some examples, the tilt sensor is anaccelerometer, directional sensor (e.g., compass), gyroscope, motionsensor, and/or a combination thereof. In some examples, the sensorincludes a biological sensor. In some examples, the biological sensor isan optical sensor positioned in the device to measure blood flowindicative of a clenched hand of the user. Some operations in method1700 are, optionally, combined, the order of some operations are,optionally, changed, and some operations are, optionally, omitted.

As described below, method 1700 provides an intuitive way forinteracting with the device. In some cases, the device performs anoperation in response to an orientation of the device. Performing anoperation in response to the orientation of the device enhances theoperability of the device by enabling the user to interact with thedevice without touching the display screen or other physical inputmechanisms. This also allows operations to be performed more quickly andefficiently with the device.

As shown in method 1700, in some embodiments, the device (1702)receives, via the sensor, a sensor input (e.g., the orientation of thedevice is changed as a result of the user lifting their arm and orrotating their wrist, as described in reference to FIGS. 11A-11B).

As shown in method 1700, in some embodiments, in response to receivingthe sensor input, the device (1704) determines whether the devicesatisfies a mode change criteria, the mode change criteria including anorientation criterion satisfied based on an orientation of theelectronic device (e.g., the orientation of the device is changed suchthat the display screen is visible to the user, as described inreference to FIGS. 11A-11B). In some examples, the mode change criteriafurther includes a time criterion that is satisfied based on maintainingthe orientation of the device for a predetermined time (e.g., device isheld for a predetermined time in an orientation where the display screenis visible to the user). In some examples, the mode change criteriafurther include, prior to satisfying the orientation criterion, amovement criterion that is satisfied when the sensor input correspondsto a predetermined pattern indicative of a particular movement of thedevice (e.g., upward movement of the user's arm). In some examples, theorientation of the device that satisfies the orientation criterioncorresponds to a raised position of the device.

As shown in method 1700, in some embodiments, in accordance with adetermination that that the mode change criteria is satisfied, thedevice (1706) transitions the device to a first mode (e.g., active modeas described in reference to FIGS. 11A-11B). The device (1708) alsomodifies the user interface to indicate that the device is in the firstmode (e.g., displays the answer call affordance 1104 and decline callaffordance 1106 of FIG. 11B or 11C, or displays the reply affordance1114 and dismiss affordance 1116 of FIG. 11D). In some examples, theuser interface includes a first graphical element associated with afirst operation (e.g., answer call affordance 1104 of FIG. 11B or 11C ordismiss affordance 1116 of FIG. 11D), and a second graphical elementassociated with a second operation (e.g., decline call affordance 1106of FIG. 11B or 11C or reply affordance 1114 of FIG. 11D). In someexamples, the device includes a haptic feedback mechanism (e.g.,vibration mechanism), and, further in accordance with the determinationthat that the mode change criteria is satisfied, the device provides ahaptic feedback, via the haptic feedback mechanism.

As shown in method 1700, in some embodiments, in accordance with adetermination that the mode change criteria is not satisfied, the device(1710) forgoes transitioning the device to the first mode (e.g., theorientation of the device is not changed such that the display screen isvisible to the user, as described in reference to FIGS. 11B-11D).

As shown in method 1700, in some embodiments, subsequent to receivingthe sensor input, the device (1712) receives a user input (e.g., userinput changing the positioning of the user's hand to a clenchedposition, as described in reference to FIGS. 9A-9H, or user inputfurther changing the orientation of the device, as described inreference to FIG. 6C-6I, 7G-7Q, 8B-8E, 8W-8Z, or 8AB-8BI). In someexamples, the user input includes receiving a tilt sensor inputassociated with movement of the electronic device. In some examples, theuser input is detected via the sensor.

As shown in method 1700, in some embodiments, in response to the userinput and in accordance with a determination that the device satisfies afirst operation criteria (e.g., user input results in graphical object614 being displayed at the end of the right track segment 610 as shownin FIG. 6G, user input corresponds to the movement indicators 708 a-708d shown in FIGS. 7B-7E, user input further changes the orientation ofthe device as described in references to FIGS. 8C-8E, 8G, 8J, 8M, 8X-8Y,8AC-8AI, 8AK-8AQ, 8AT-8AZ, or 8BB-8BH, and/or user input changes thepositioning of the user's hand to a clenched position as shown in FIG.9C), the first operation criteria including a mode criterion that issatisfied when the device is in the first mode, the device (1714)performs a first operation (e.g., answers an incoming telephone call,declines the incoming call, displays a reply interface for a receivedinstant message, or dismisses the received instant message). In someexamples, the first operation criteria further includes a first tiltcriterion that is satisfied when the device is rotated in a firstdirection around a central axis from a neutral position to a firstposition (e.g., the display screen is rotated away from or toward theuser). In some examples, the first tilt criterion further includes arotation criterion that is satisfied when the device is rotated from thefirst position back toward the neutral position within a predeterminedtime (e.g., the user makes a “flicking” motion with the device, wherethe display screen is quickly rotated in a first direction and then isimmediately rotated back in the opposite direction). In some examples,the central axis corresponds to an axis of rotation of a user's wrist.In some examples, the first operation criteria further includes a handposition criterion that is satisfied when the user input corresponds toa predefined pattern for a predetermined time, the predefined patternbeing associated with positioning of the user's hand (e.g., the userholds their hand in a clenched position for a predetermined amount oftime such as shown in FIGS. 9C-9G). In some examples, in accordance withthe determination that the device satisfies the first operationcriteria, the device (1720) optionally modifies a visual appearance ofthe first graphical element (e.g., the first graphical element isenlarged in size, the first graphical element moves toward a centerregion of the display screen, and/or a progress ring is displayed). Insome examples, the first graphical element is a first affordanceassociated with an answer call operation (e.g., answer call affordance1104 of FIG. 11B or 11C).

In some examples, in response to the user input and in accordance with adetermination that the device satisfies a second operation criteria, thesecond operation criteria including a criterion that is satisfied whenthe device is in the first mode, the device (1718) optionally performs asecond operation (e.g., answers an incoming telephone call, declines theincoming call, displays a reply interface for a received instantmessage, or dismisses the received instant message). The secondoperation criteria is different than the first operation criteria andthe second operation is different than the first operation. In someexamples, the second operation criteria includes a second tilt criterionthat is satisfied when the electronic device is rotated in a seconddirection around a central axis from a neutral position to a secondposition (e.g., the display screen is rotated away from or toward theuser). In some examples, the second tilt criterion further includesrotation from the second position back toward the neutral positionwithin a predetermined time (e.g., the user makes a “flicking” motionwith the device, where the display screen is quickly rotated in a firstdirection and then is immediately rotated back in the oppositedirection). In some examples, the central axis corresponds to an axis ofrotation of a user's wrist. In some examples, in accordance with thedetermination that the device satisfies the second operation criteria,the device (1722) optionally modifies a visual appearance of the secondgraphical element (e.g., the second graphical element is enlarged insize, the second graphical element moves toward a center region of thedisplay screen, and/or a progress ring is displayed). In some examples,the second graphical element is a second affordance associated with adecline call operation (e.g., decline call affordance 1106 of FIG. 11Bor 11C).

Performing the first or second operations in response to receiving auser input after an orientation criterion is satisfied allows the deviceto be operated with fewer physical inputs from the user (e.g. fingertouches on the display screen). Reducing the number of inputs needed toperform an operation enhances the operability of the device and makesthe user-device interface more efficient (e.g., by helping the user toprovide proper inputs and reducing user mistakes whenoperating/interacting with the device) which, additionally, reducespower usage and improves battery life of the device by enabling the userto use the device more quickly and efficiently.

As shown in method 1700, in some embodiments, in accordance with adetermination that the device does not satisfy the first operationcriteria (e.g., user input does not result in graphical object 614 beingdisplayed at the end of the right track segment 610 as shown in FIG. 6G,user input does not correspond to the movement indicators 708 a-708 dshown in FIGS. 7B-7E, user input does not change the orientation of thedevice as described in references to FIG. 8C-8E, 8G, 8J, 8M, 8X-8Y,8AC-8AI, 8AK-8AQ, 8AT-8AZ, or 8BB-8BH, and/or user input does not changethe positioning of the user's hand to a clenched position as shown inFIG. 9C), the device (1716) forgoes performing the first operation.

In some examples, in response to the user input and in accordance with adetermination that the device does not satisfy the first operationcriteria, performing a third operation, wherein the third operation isdifferent than the first operation and the second operation (e.g., thedevice displays a time or a default “home” interface).

Note that details of the processes described above with respect tomethod 1700 (e.g., FIG. 17A-17B) are also applicable in an analogousmanner to other methods described herein. For example, method 1700optionally includes one or more of the characteristics of the variousmethods described above with reference to methods 1200, 1300, 1400,1500, or 1600. For example, the mode change criteria of method 1700 canbe satisfied prior to receiving the biological sensor input of method1500 (e.g., the display screen is held in view of a user for apredetermined time as a precondition to receiving the biological sensorinput). For brevity, these details are not repeated above.
